I swear some people just see 'Mousemat' in a thread name and copy/paste 'Boogiebug' into it. He asked for a RIGID mat and the Boogie is clearly not rigid. You guys using an IceMat are missing out on modern tech. I used an IceMat for 4 years before Steelseries acquired the company and began producing them under a different name. I too believed it was the best around, until I tried my friends cloth Qck. Promptly bought one and havent looked back.
If you're set on a solid plastic mat (personally I don't understand why anyone would be in 2012, with the evolution of cloth mats) then look into the Razer Scarab or Steelseries 4/9HD. Both will exceed your expectations if you're coming from an IceMat.
