My former home rack was an open-top, 2x2, with front uprights lower than the back. It worked well enough, but it wasn't very deep (only about two feet between front & back uprights - wife hated that), wasn't very tall (so no press lockouts or chinups) and the safeties couldn't go low enough for flat benching (exciting at times, but not recommended). The lower front uprights made it easy to switch from squats/overhead press to floor lifts, as I could rack the bar, walk it out/clean it, walk it back in, which I really liked. Never had an issue with losing balance and going backwards. I never used the lat attachment, but would have preferred some kind of overhead bar for chins/pulls. When my squats approached 300, however, I started getting nervous, as the tube construction would flex a bit, and had visions of the rack tipping over (never happened, though). My humble opinion: only buy it if it's cheap, and you can save $ for a full rack later on.
