Tool Project Centers & Work Carts

So I purchased a lathe a while back that came with a crappy little Craftsman tool chest. It was bolted to the top with a piece of plywood as a top work surface.

At work I have been eying a very nice Westward project center, however, at $590 it is WAY over priced for what you get.

It has a nice galvanized top and light as well as power outlets. Not to mention the pegboard back.

Grainger also sells a unit without the backboard for $354. These units DO have ball bearing slides. As it turns out, the Westward units are made by Waterloo which is the same company that makes Craftsman units.

Waterloo manufactures a lower quality unit for Craftsman based on the same design. The Craftsman unit sells for just $149 (regular $199), but lacks ball bearing slides.

I have used the above unit before and after a while the non-BB slides make it useless. So it is worth getting a unit with stronger ball bearings. For $200 I feel I should be able to get a BB unit! You loose a lot of features though on the two units above over the unit I first mentioned. The features lost are the ones that are most important too me. So my idea is to get a quality bottom tool cart/chest at a good price on sale and convert it to the unit on top for a total price of $200-$250.

On eBay I managed to find a discontinued accessory to the Craftsman tool cart which would allow one to add the backboard and light to your basic model.
