The Panny is out of prod and very difficult to find. You can easily find the 2 Mitsubishi units. JVC has the 3000 with D-Theater, which will soon be joined by two more JVC units-- the 4000 model (supposed to support DTS) and a Professional model. A Marantz version of either the 3000 or 4000 is expected this summer. It is a D-Theater machine as well.
Also, there are several STD D-VHS recorders-- Hitachi, Hughes, and a DISH Network box with a built-in JVC d-vhs unit. These models will only record 480i-- no HD.
