I have been trolling Ebay for a few weeks now...I can get a 700 series unit for around $350 and a 900/90 series for around $450. I am unsure of what I am giving up for the extra $100 between the 700 and 900 series units. The features seem to be identical.

 

Any help with the decision?

the units are the same except for the f900 has a high gloss black face(the f700 has a flat black face), a DVD player, and a video out (it also has MSN direct, but that service is getting discontinued)

 

the F90 has all the above and the RCA preouts jump up from 2volts to 4volts.
