I like my PVC racks. And if you wait, you can maybe find some on sale.

I got my first two for 20% off as a presale to an expo:


I have:
1 10 slot 6qt rack
1 5 slot 28qt rack
1 4 slot 41 qt rack.

The 41 qt rack is made by boaphile. I found it on a classified website and it's definitely not my favorite. It's a bit heavy and a bit wobbly.

My other two are awesome and super light. They're also made to stack, and we're fairly cheap.

If you have the skills to make you're own, do so. I'm just not handy, and would rather have the proper equipment. Knowing me I'd screw a rack up royally.
