Dang those aren't cheap that's for sure.My favorite version is this one:
They also have one that is more like a flat at my main gym. I get about the same weight on either but getting set is easier on this one. You can get a better deal even on the stack plate version with weights.
Another thing i've been throwing around within the next few years I'd like to get a Force USA G20 all in one trainer for my home gym but those are like $6k
