personally i think it's the best all rounder. it does everything and for a decent price too.
people usually go for the powerhouse fitness racks and equipment because money is an issue, but tbh it pays to spend a little more initially.
better rack, dip bars, pull up bars, lat pulley option, looks great too.
the body solid one is probably overkill, although a better rack, gymratz make even better racks and i have another company in my bookmarks somewhere that make the best in the UK, but they are so expensive they would bring a tear to your eye.
you can't go wrong with the powertec, so it should be an easy option tbh.
changing weights on the pulley isn't a huge issue if you buy plates with "handles" and buy a storage rack.
it can be a pain though if you have all your weights on the ground and no handles to easily lift them around with.
