We've got a thread entitled "Buyer's Remorse" so let's go the opposite direction and post our best deals.
I just bought a new Dean El Diente ti frameset with custom paint for $925.
And, using the 20% discount coupon from Performance out-fitted it with wonderful gear (ti/mg pedals $52/pair, carbon bottle cages $16 each, FSA carbon crankset for $270, etc.) and then get another 10% credit for future purchases from Performance.
What have you done well with?
