The CAP OB86B (not the power version, which I haven't seen) can be had for just about $100.
I have two. The coating is so grippy, you'll never miss center knurl. It has fairly sharp knurl.
The Cap is not junk. Not at all. Though if you have $300, you should get something better.
I have the Ohio. I probably should have got the Ohio Power (thought I'm not sure it was out when I got the Ohio bar.)
There is a lot of discussion on bars in the Garage Gym thread. And there was a very recent thread called something like "what second bar should I buy".
