Check out the kokatat mass on eBay if you don't need a tunnel for a spray skirt. You can find them for a couple hundred bucks, and they are full gortex, with a bunch of pockets, socks, and the relief zipper. They even have some built in soft shin/knee guards. Basically a gmer on steroids, and since they are issued to a lot of marines, they end up on eBay brand new frequently. I love mine, it is the best suit out there for class 4-5 rubber pushing in my opinion. Also the pockets are amazingly useful. The only draw backs are that they aren't the lightest dry suit out there, but they are tough enough to handle some serious abuse.
