Thanks to everyone for their responses. I went with the Simms G3 waders. I'm not sure I would have bought them at full price, but at 40% off, I couldn't resist a (relative) bargain. I've owned Simms breatheables in the past, and the product was good. The service was lacking, but many people rave about their service, so maybe it's improved since then. I hope I don't need to find out.
