My understanding is that everything in the <$10,000 range is still one-chip with a color wheel. As you have already realized, the HD2+ is a single chip, as are the HD3 and the xHD3.

(This thread and future similar ones would probably be better suited to the Outlaw to Outlaw or My Systems Saloons than the "Suggest a Saloon" area, but don't sweat it -- no harm done. )
