Something that boggles my mind - how come the TUPT600 Panasonic tuner (for PW7 plasma) is more expensive than a Panasonic DVD-Recorder WITH a tuner built-in ? I see a certian disadvantage to using the TUPT600 - the plasma is blocked for other input boards when the TUPT one is connected. This means PiP is lost if i understand this correct. Then it's also an additional device + cabling. If i'd take the E55 DVD-Recorder - i get it all at once, a dvd recorder and a tuner, plus I will not block my plasma's PiP function. Furthermore - it's LESS expensive. What's the advantage of the TUPT600 to make it that more expensive ?
