I got my John Howard frame built by Dave Tesch on the cheap because the seller did not take good photographs. Many people must've figured it was a KHS and moved on.
The fixie craze has jacked up prices on a lot of components but left others alone and often starving for attention.
I've noticed a Super Record RD going for peanuts while an identical one gets top dollar; both on auction at the same time.
I appreciate Campagnolo going to a new crankset design. Their square taper cranksets are now much cheaper. I've gotten two Record 53-39 cranksets, NIB, for $100 plus shipping apiece.
I let the fanatics go crazy over C-Record and grab Daytona, Athena, Chorus or even Record components at much lower prices.
I then use my money saved to get outrageous paintjobs.
