If you can get your hands on one of these stations, you are good to go.
Prospot Fusion (or sometimes listed as Prospot Fitness) had a very unique aspect of being a smith machine type but with a free motion bar. no poles, rails or tracks. To rack the weight you simply let go of the bar and it locked in place where ever it was.
Company went bankrupt mostly due to being very expensive to start with... but if you can find one it is generally really cheap.
Lurker looks decent enough. But its still barbell movements, benching, etc. I was thinking more for the person who's joints are shot from 40+ years of this stuff.
Weird on your buddy's PowerTec, I would think its easy on the joints, maybe for some and not others depending on the limb-length, levers?
I tried a Bowflex once but didnt like the feel of it (wand-wobble). They'll probably come up with many more machines by the time Im at that point.
That Pro-Spot was on to something though, the space saving, the leg-press piece and other attachments. Interesting. Maybe Basile can design one for us all.
