I'm not sure what you mean as far as the pre-made ones off e-bay but dry gloves are worth $100 - easy.
Many out there are good. I have used the ringless ones mentioned above and prefer them, but got tired of dropping over a hundred bucks ever time the latex went bad. I moved to rings. First were the old style Viking rings and currently the Viking Bayonet style. Aside from the fact that I don't really "dig" the rings getting in the way all the time (although you get used to it) I really do like the Bayonet rings. Never had a leak and their very easy to put on.
Good luck,
Hunter
