This may be too late now, but I've recently been doing a bit of wader shopping. I ruled out anything over $350 because I just don't see the reason to spend that much when there are plenty of waders available for under $350 that have solid reputations. I looked at Grey's GRX, Guideline Techstretch, Reddington CPS, Patagonia Watermaster II's and William Joseph V2's. I ended up getting the Guideline Techstretch (and so far love them) because they fit the best for me, tall and thin. As well, I think these are damn close to equal, if not equal, to the Simms G3's and more supple. These are sweet waders. However, I would have purchased any of these waders based on my research. Depending upon where you are, any of them can be found on sale somewhere. I still have a pair of older Wardell's as did my brother, but found the material to be a bit on the rigid side. As well, I understand that the newer ones are not made locally, but offshore and have had some leaking problems. I also still have an older pair of Bare lightweight travel waders that are not very breathable, but have lasted for years.
BTW, I fish about 12-15 days per year.
Those are my two bits.
Cheers,
Mark
