I tried typing this out before but I guess it didn't get submitted? oh well
Update on the bike and computer situation:

Finally found (what I think) was a very good deal. A 2009 Felt f85 for $500 on craigslist. I met the guy today (about 50 miles or so away from my house, but worth it) and inspected the bike a bit. The wheel's slightly out of true, but other than that it seems to be in pristine condition. shifted smoothly, silent, well oiled chain, brakes worked great. full 105 groupset
I was able to haggle the guy down a little, so I was able to get the bike for $475. after a long drive back home, I fixed the wheels, and it runs beautifully. It has flat pedals on it, but I was able to score sidi genius shoes with look cleats and pedals on ebay for $65, so that's no problem. I also got a sigma bc 1609 computer that I was able to mount after about 45 minutes (had to run to the dollar store and get more zip ties).
Just placed an order on amazon for a new avenir seat bag, carbon water cage, another polar bottle (you can never have enough, right? ) and a frame pump.

One question I do have though, what are the pros/cons of mounting aerobars to it? I wanted to get some and put them on, but I'm not sure if that's a good idea or not.

oh, and of course, pics! (feel free to ignore the random stuff in the back ground)
