The one I've been using came off the "Job Lot" bargain rack @3mm for about $50.
Using an UA shirt and shorts = NO rashing for me

as well as making sliding in and out of it pretty easy.
Fits me solid, no bunching up. Really no complaints other than freezing my

off when undressing at the truck. For the $$$ It's held up pretty decent. The only spots that could use some love would be the knee areas from all the praying I do on those barnacle covered rocks...
Like you said, this could be a thread for someone buying their first suit...and for those of us with a limited amount of "play" dough....this was a bargain, and allows me to get anywhere you deep pocketeers can go. As far as hating my waders...NEVER. Nothing beats the feeling of getting back to your truck, dropping your waders and being bone dry. However....the
NUMEROUS advantages of wet-suiting clearly surpass the disadvantage of being "wet" after-wards,....
Sorry that this didn't help you any....
