All the HD's around here (metro Detroit) only carry the non-SP version. I had to order the SP 21" from their website and won't get it for another week. :( That said, I picked up the regular non-SP 21" for the time being but will return it once I get the SP. Sucks that HD will have an open-box return of used OPE, but they should stock the SP version.
Let us know your thoughts after you spend some time with it!
