I have to throw out my opinion, and that is the Barefoot Int'l suits.
The material and seals seem a little more heavy duty, and the biggest plus in my book is the neoprene cinch cuffs over the ankle and wrist seals. Not only does it protect the seals, but you can also cinch the cuffs down over booties or gloves on those really cold days, and keep the water transfer very minimal.
If you are in the market for a budget suit, check out the Overtons Gladiator suits. Being that is our "local" shop, alot of ppl around here have them. They seem to work well, but the seals are a little thinner, which means just be a little more careful taking off/putting on, but I believe it is on sale right now.
