Commuting - Motobecane 10 Speed... Good for upgrade?

I posted a while ago with another question and got a lot of helpful advice so I thought I'd check with this one. I've been trying to find a cheap commute bike so that I don't have to rely as much on my Blast and keep it more for off-roading. I figured that a cheap used road bike would be the way to go so I've been visiting local pawn shops and seeing what they have.

I recently was offered a slightly beat up Motobecane 10-speed that looked like it was from the mid-80s or before. I didn't have much time to take a close look at the componentry but noticed that it would require a good bit of work (rims were not only out of true, but just warped all around; new tires, new cables and possibly shifters... etc) and it didn't appear to have full braze-ons for a rear rack (something I really would like for commuting). However, he was offering it for $10. Right now I'm very busy with work and getting ready for getting married, so spare time is a bit of an issue, but do you think that it would be a good idea to get it and just fix it up, or should I keep my nose to the grindstone and keep looking for something a bit more ready to go. It appeared to be the right size for me which is a rarity (I'm 6'4").

Any input you may have would help. Also, if I were to get it, could I upgrade the cassette for a little more options in gearing? Thanks...

For $10, what can you lose?

I think it has potential for $10. My approach with 10 speed commuters is to replace the front brake pads, tires and tubes (Nashbar about $30 + shipping). I saw 27" tires in one of the flyers for half price ($4.95 each). Next step is to wire brush (tooth brush size) anything with rust, wipe off with solvent then lubricate heavily. I would get the front tire as true as possible so I could use the front brake. Let the rear tire wobble a little and your done in about an hour total time.

You could also keep your eyes peeled for another 10 speed and use the rims from that one. Motobecane made nice bikes ... you could invest another $50 and it would still be money well spent.

Like all major marquees, MBK made some great bikes and a great many entry level anchors. If the frame is a good one, go for it. Otherwise I would keep looking. For a long time I always tried to get my thrift store finds for $10 or less. More recently, I have had to up that to $20 or less (Inflation you know) but my goal was always a completely useable bike or at least a quality part. If you look a bit, you may find aother great vintage lightweight that just needs a cleanup & lube! Don

Check it out throughly before buying. Turn the bike over, look for cracks and dents. Take out the rear wheel, run a string from one dropout, around the head tube, and then back to the other dropout. Measure the distance from the string to the seat tube on both sides; if the distance is the same, good. Loosen the seatpost bolt, grab the seat, and twist, to make sure the post isn't frozen in the frame. Loosen the nut that holds the stem in the steerer tube and make sure the stem isn't stuck, either (you may have to tap the nut to loosen the stem).
