Actually, this post probably belongs in the "Kitchen Equipment & Gadgets forum" - until then....
My grandparents had an old G.E. unit that really busted through lots of meat in short order. It actually had a piece of hardened (carbide?) metal embedded in the edge of each of the two blades. Don't know if anybody makes new ones like that or not (like almost everything else, they've probably gotten cheaper, but not necessarily BETTER.) Some of the new ones have cords so short that you'll need an extension cord to make them useful.
If you do not mind the ugly green color, the Rapala Electric Fish Fillet system actually works pretty good - my friend has one, and it has seemed to hold-up over the past few years.
I also prefer a sharp carving knife set - I've heard good things about the hollow-ground carvers (with hollowed-out depressions in the flat sides of the blade), but have not used one myself.
