What's your max lift?
I bought a decent 300lb set from Sport's Authority for $109. The bar is not the best, the knurl is smoothed down, but it's good enough for starters. The plates are better than the bar.
You can invest in a better bar later on.
I bought bar from fitness factory so that I can do front squats without the knurl scraping my neck. It's solid, has excellent knurling, supports 1500lbs, is 200,000lb tensile strength, etc, at a pretty good price.
