what would you do? Fix it or buy new?

i have a 5 yr old custom steel trail frame with a white bros fork, and full xt, i finally broke a chain last week, and after purchasing a new one, it started skipping, indicating a worn drive train. Im going to college and work part time, and have been eyeing the trek remedy 5. I just got this job about 2 weeks ago, and have decided to start saving $100 a week. Would you part the bike out, leaving you with no bike for the next 6 months, or would you stop saving for the trek and pay to get this bike repaired?
ive been debating this for the last week, and im not getting anywhere.
i ride 4 days a week, i dont really have any sentimental value to this bike, but im broke and have no plans to quit college to work full time to pay for my biking mishaps.... i also have no plans to go out and steal a new bike; although, that would take care of my woes... what would you do?
The chain skips only on the lowest 3 cassette gears, which are replaceable, but i dont want to spend the money on those, then find out its the jockeys or chain rings that are the problem.

same thing happened to my commuter last week...skipping got so bad that only my granny worked

Looked at used bikes, cheap, and inexpensive bikes, but I wasn't able to find a frame that came close, and the comonents on the cheap/inexpensive bikes were a joke.

Ended up replacing the bottom bracket, crank, cassette, and chain...about $220 cdn, but worth it...the bike now runs better than new

And I like that old Schwinn frame (Sierra 700 GSX)...one of the last U.S. built Schwinns

may need a new crank as well...usually when the chain stretches it takes the chain rings as well...easy to check, if the teeth have sharp points, it's shot, same with the cogs

Buying a new bike is always a great pleasure, but if you're on budget just stick to your old one once you'll repair it. With your old bike you'll never be afraid to get your new one stolen.

Spend the money on a new cassette, or if possible those three cogs

Good thing those chain rings are replaceable. Buying a new crank every time a ring wore out would suck

Another cheap fix for chainrings is to flip them around. You'll get a few more miles out of them without investing in new rings. They won't be as good as new rings, but they will likely be an improvement.

Start with the cassette, and see if that improves things. If it doesn't, flip the rings.

Is it skipping, or are you getting ghost shifting? Ghost shifting could indicate a weak rear derailleur spring.

Regardless, I'd fix the bike you have. If your frame fits, why replace it?

CRANK?...no
Middle ring probably needs to be replaced. I get way more miles out of the granny, and big rings.

after the advice, i think im going to fix it.
i look at the cassette and it looks brand new. the teeth are still sharp and the chainrings still have the black paint. im going to start with the jockeys and see if that might be the problem. they are the only thing in the drive train that looks worn.
i guess ill have that all mountain rig in time for the 09 riding season.

Also check to make sure your cassette lockring is tight. I was getting sloppy shifting and while doing routine maintenance & cleaning discovered that the lockring was so loose that the cogs could move ~2mm side to side.

im glad you mentioned that, because when i bought the new chain before i put it on, i serviced the entire bike, and took apart the hub. the first time i put the lockring back on, it wasnt tight enough, and now that ive retightened it, i dont remember if the lock ring sits flush to the first gear, or if there is a lip. the park cassette remover is stripped, so i dont have any idea if i can tighten it more.
i checked shimanos website, because they have exploded views and service instructions, but i cant find a picture of the cassette with the lock ring in place. im going to post a quick microsoft paint drawing to show you what im talking about:

anyone know what its supposed to look like?

Do the cogs wiggle at all? If not, I'd say it's probably OK as is. It'd probably be a good idea to pick up another cassette tool to tighten it, though, just to be safe.

i dont feel them moving, but the lock ring washer could be preventing them from moving except under force, which is the only time it skips. i like to think of myself as a 'do it yourselfer' but i just talked to my mechanic and am going to take the rear wheel in to see what she can find. i also just ordered three new chainrings, so that wont be an issue.

well thanks to everyone who gave me advice. i took the wheel in and she loosened the lockring and found that the flimsy washer was kinked preventing the ring from sitting securely. she replaced it and now it sits flush to the first gear.. so if anyone ever asks that question again, the m760 lockring sits flush to the first gear. i bought some charmichael jockeys and went for a ride, and had no problem with slippage.

check your shifter cable also...sometimes they bind and make it seem like its skipping.
