Being a bargain biker myself, one option I definitely recommend is looking on eBay for a set of used Avid’s, Haye’s, Formula’s, or any other good brakes. You can find some really good deals for some good brakes. My friend and I have gotten numerous deals on slightly used parts. For instance, my friend recently bought an X-9 rear derailleur and shifters for probably about a third of retail price, and they are in excellent condition and work great.
