Wow, I've the exact opposite experience. The last gym I worked at had nothing but powertec in the back room, for private clients only. Well, it's the cheapest equipment I've ever dealth with. You know what, to be fair, if you're not going to use a decent amount of weight I guess it's okay. This gym had the T-bar row, lat pull down, flat bench, hack squat, and a few other pieces. The "metal" bent, the joints were loose and would shake....very poor quality. After a few months the gym owner put them on sale...for cheap. VERY CHEAP!
my two cents, good luck and make sure that you can send it back if you're not happy.
