dude.. thats not a squat rack.. atleast not that i know. That in the link there wouldnt be free weights, which is what you need.
This would be a squat rack: http://www.roksport.com/acatalog/SR50_squat_rack_lg.jpg Its just a place to have the bar at your height level and use for loading/deloating the bar. (im NOT saying that is a good squatrack to buy, i just googled an image)

I know alot of people could have good recommendationes to what home eq to buy. Personally i dont have any experience. But it could be smart to buy one that comes with a chinup bar etc.

yeah i know it isnt, but you can do squats with it, was just wondering if any1 had used it or heard any feedback on it.
