I use the Pf60 and I belive that I did suggest Gonk to use one :-)

Turns out I got the pF60 from Newegg for $199. Nice unit. Initially I was shocked at the size of the thing, esp the power cord. The current and Voltage are easy enough to see and the dimming feature is extremely useful. Amusingly enough, after I connected everything, I played a dvd of a series I enjoy and was taken aback. The picture looked ever so slightly..off. Naturally, I thought the PF 60 was to blame. As a quick check, I put in the dvd disc 4 of the series in ( I was watching number 5 ) and was floored as to the picture quality. Nice and sharp. Clearer than I remember anyway. So the unit is a keeper! Thanks to all for the information posted.
