I purchased this barbell for my home gym.
It's 45lbs, has a 600lbs limit and I haven't had any issues with it so far. My concern was the hex nuts on the collars coming loose during O-lifts, but I have not had to tighten them yet (3 weeks daily use).
I needed a bar to lift with while I outfit my gym over the next 6 months. This bar is exactly that.

Get plates at your local sports store or Wal mart. I used a similar set up for 10+ years before the bushings in my barbell wore out.
