I feel ya. I'm still doing the ebay game to hopefully replace some of my underperforming pipes, but I'm being extremely choosey, only looking for absolute steals(my goal is to pay between 10-20 dollars per pipe, having researched seconds and lesser known brands that are good bets). This would have been effortless 10+ years ago, I remember you could reliably find lots of very good pipes for absurdly cheap prices-- lots of people didn't know what they were selling back then or perhaps assumed there was no market for pipes that were already smoked. Pipe prices in general have gone up over the years I think, not just for ebay estates.
Still sad about a quality author pipe that was sniped at 01 seconds a few days ago
But each loss is a lesson, if I really like a pipe I should bid a little extra. Not sure it would have mattered in that case because if someone's resorted to sniping software usually they will get what they want and make sure you're beat.
Nonetheless, I remind myself to be grateful for the good smokers I already have and that with patience, eventually I will land on more good pipes for a great price, even if it's a little harder to find these days.
