I looked a these at the store the last time I was there. Not the best but not bad at this price.http://www.harborfreightusa.com/html...9/images/3.gif

Take a look at Grizzly http://www.grizzly.com/products/item...emnumber=H0683 .
Only 20¢ more (plus shipping, of course)

I've used several sets of those and the 4" versions and have been very happy with them. Have one cabinet that hadn't been moved in two years and the wheels were still round, no flat spots.

These are the best I have used. They are a lot like the Woodcraft ones but cost less.http://www.hartvilletool.com/product/11883

I seem to never be able to plan ahead for this purchase. I seem to always build it with cheap ones and end up replacing them down the road.
