I spent a lot of time and money on searching for a saddle; finally wound up riding a Selle SLR Gel Max Flo that goes for around $200. No biggie, but not cheap.
Few years later I see that those are on sale online for $98. Score! I order another ... and they'd completely re-configured the saddle. I double- and triple-checked ... nah, not my imagination. What once was a cracker-flat saddle now featured undulating front-to-back curves, and more gel than previously (both are stamped L3).
Drives me nuts.
