Since all of my discretionary budget is going towards our as-yet unborn puppy, I will just be making essential repairs to my current bike. The rear derailer is worn out. I think I can replace it with a decent one for under $50. Used or really good sale items are being scanned. I want a fairly large chain wrap capacity on this bike, so I'll pobably will go with a GS type or something like Deore.

Thoughts?
