I personally got an Toshiba folio 100.
they do not appear to sell that much any more, both Toshiba and retail stores give massive discounts, due to the ROM (operating system) it comes with.
HOWEVER, install foliomod and BAM! awesome tablet!
you NEED foliomod though, fixes the touch screen and multi touch drivers, increases performance by far (it has a nividia chip in it! damn fast!), android market, rooted, launcherPRO!
I got 50% off (and it was worth that much with the stock ROM) but it really is worth it if you search a little on the internet.
