Bottom of the line-as it turns out! It's the sport CS (i think it's CS, maybe CX). It seems to be in pretty good condition. There's actually pic's of it on my blog right now..feel free to follow the link below.

I ended up picking it up for $35. I'm fortunate to have a great bike co-op here in town. The guys there will be very happy to teach me how to work on it. Then, worse case scenario, if it really doesn't work out for me, I can donate it to the co-op.

I've been doing some research, I'd love to find a DX model in the future!
