Well, I've gone through my share of waders.
Hodgeman's. 3 pairs leaked on me, each of them leaked under a year and finally got replaced right about at a year. Heavy use though. No holes, the fabric just stopped being waterproof. They are easy on the wallet upfront, and were very comfortable, though.
Since then I've been an Orvis guy. The cheapo model (currently called Endura, they were about $130 at FFP) lasted me 2 years of heavy use before first leak and were replaced at about 2 1/2 years. My current pair are Silver Labels, which just hit 3 years and sprung the first (minor) leak shortly thereafter. Haven't yet gotten around to seeing if its fixable. I think they ran me right around $200. Love the easy conversion to waste-highs, though. Most waders say they can convert but few are as natural a conversion as the Silver Labels.
