I'm pretty partial to Body Solid. I got my Smith Machine with weight stack up to 180 lbs (can also add weight), a plate loaded pec dec, plate loaded/chest supported seated row, seated calf raise, 2 in 1 seated leg extension/leg curl, dip bar & leg press from them.
Have since sold the leg press/seated calf raise (can't work legs due to knees).
Also bought a seated dip machine for like $100 on Ebay a while back.
Also have about 1200 lbs in free weight, Power Block dumbbells that can be adjusted up to 125 lbs, a trap deadlift bar, swiss bar and an Olympic bar.
Oh yeah, and a Powertec power rack with pullup attachment.
EDIT: Powertec products are very affordable and a quality product, btw.
