I have a promaxima barbell, because at the the time it was literally the only barbell available and i probably paid way too much for it but it got the job done. I also had many of their rubber coated plates which are nicely made with the exception of being 1.8 inches shorter than a standard 45. Not really into deficit deadlifts unless i really have to.
They're equipment looks really decent though. I'd say as long as you can get it for a decent price id go for it. If your putting a lot of money out i would go with something from rogue or elitefts just because in my opinion the promaxima equipment could be designed slightly better. Im sure it still works great, its just an expensive item so I would say do your research. Im not really sure what the retail is because they don't list it and its hard to find it for sale anywhere accept one place i know of.
Just out of curiosity are you getting this from "buy and sell fitness", near the Orlando area?
