Where to find good pulleys

I'm hanging my kayak from the ceiling of my garage, and I bought some cheap pulleys from Harbor Freight to setup a simple block & tackle style rig. It works, but the pulleys are relatively cheap, and they bind easily. I went to West Marine and looked at their pulleys which were significantly nicer, but were also around $25 each.

I'd love a good recommendation for pulleys that won't break the bank. It's hard to tell what brands are good when you're looking online.

Thanks
