Share 'Chocolate Dude Tabletop Tempering Machine'

Has anyone bought one of these Chocolate Dude Tabletop Tempering Machine http://bakerscandc.web-ctr.net/product_info.php?manufacturers_id=14&products_id=676&osCsid=aaeb741eaeef1f59ea63733931a509d9 It seems like a bargain at 12 lb capacity for only $525, equivalent about to the 1.5 lb Chocovision Rev1, so what's the catch? Do they have temp control problems? Do they not stir? Why so cheap…
