I'd take a look at the Orvis Silver Sonic waders. Cheaper than the Redingtons and the same technology. You lose the handwarmer pocket but gain a cool flip out waterproof pocket for cell phones/keys etc. Orvis treats people right as far as customer service as well.
All waders will get pinhole leaks. They are all practically the same material. The difference seems to be in how well-constructed they are. The new Orvis and Redington waders have just about proven themselves as the best wader for under $300.
I have the Silver Sonics, and I feel like with a tube or two of Aquaseal they should give me 2-3 years no problem.
The convertible to waist-high feature is nice, too. It makes wading a 50-degree creek on a warm day a lot easier, and it's easy to pee.
My Muck bootfoot Simms have more Aquaseal than Gore-Tex on them now after about 4 or 5 years of abuse. I'm looking to replace them and have been eye balling the Orvis bootfoots. The only thing is it looks like they have no chest pocket. I never wear a vest or anything. Everything I need goes in my chest pocket. The search for the perfect bootfoot continues. Off to the store to get another tube of Aquaseal.
