Ten years ago I bought a pair of Diadoras in a shop and they're still my primary shoes (I didn't ride all that time). A while back I bought another pair of them off ebay for $10 (brand new).

I also have a $200+ pair of Sidis in the closet that I haven't even put cleats on yet. I bought them on a whim and then decided it was pointless to bring them out until the others died.

Anyway, my point is that there are plenty of deals on ebay, and you don't have to spend a fortune to get something comfortable. Go out and learn what brands fit you correctly, what sizes you need in each, and then sit back and wait for a deal.
