I have a bike dilemma that I would like some advice on. Here's the background:

My winter bike is an almost 10-year-old Specialized Hard Rock. I paid $500 for her new. I love her dearly although she's covered in rust and stickers. After this winter -- it was a hard winter in New England -- I took her to the bike shop for an estimate of the damages. Well, knock me over with a feather: It would cost $620 to get her back into good working order. I'd have to replace virtually everything but the frame and the wheels.

Should I fix her up, or should I buy a new winter bike? (I'll be moving to Seattle, hopefully before winter, so the extreme snow/salt thing won't be as much of an issue in the future.)
