Us Cannuks have more issues with Flexxwatt than others. If you burn down your place with Flexxwatt your on the hook big time.

If you can avoid it, great.

Melamine is probably your cheapest option, and your easiest to work with.

If you have facebook check out Mike Lopez to get ideas. His are as basic as they come, it's what I have, but it's easy as hell to make. I am lazy and would rather someone else make it for me. And his design works great! One of the best racks I ever owned.

Goodluck!
Cheers.
