Has anyone tried these?

[deadhead]

I ran across this while checking out the new Pearl Travel Conga: [url=http://www.pearleurope.com/pearleurope.asp?contentpage=%2Fcontent%2Fproducts%2Fdefault%2Easp?classmainid=4^classsubid=32^classsubsubid=^productid=136]Pearl Reso-Plate[/url]

Wondering if anyone has used these. Seems like a good idea, but $30ea!? How different would it be to put a sheet of plywood down tho? Home depot sells MDF rounds for like $4ea, I bet there is minimal difference.

I made my own just that way...work great, since I play on carpet alot.
God bless!
