a couple things:

1. as was said before you get what you pay for..
secondly Simms has discontinued most of if not all of their neoprene waders.
They can still be found in fly shops at closeout prices I have seen them at 99 dollars.
They are discontinued because everyone is buying gortex. Lots of shops can't get rid of their neoprenes even at the closeout prices so you should be able to find some..

Also what you wear under your waders is equally as important as your waders themselves. NEVER wear jeans!! wear some kind of pants that have wicking propertys. fleece and polypropelene(sp?) are the best and get some nice smartwool socks even if your waders do leak a little your feet will stay warm..

I have had lots of hodgeman waders all of them leaked after short periods of use...
