Ironmind.com has some decent barbells. If you really want high end and super strong (think handling over 1000 pounds easily), the S-cubed bar they have can do it but it's costly, around a whopping 400 bucks.
For something that can handle some good weight and isn't too terribly priced ($220), plus to make your training more intense while getting you a grip that would make a vise jealous, you could try their Apollon's Axle. It's 2 inches thick around.
