I'm speaking more of home gym setups personally but I wouldn't limit to them either. Like currently I'm trying to find a machine like this
It's the Nautilus NT-CC1. I like it very much for the fact that the Cable crossovers are adjustable. It's perfect for my garage because space is limited. Smith machine, cable crossovers in one machine.
I also like the Bodycraft F660 Hip Sled
This thing is sweet. You can do hack squats, leg presses and donkey calf raises on it.
Those two machines would make a nice addition to my current setup. I just think it would be cool to have a little background info and reviews on machines before investing that kinda money.
