im leaning toward the 90, but which unit do you all recommend?

the f90bt is actually cheaper off of ebay then the 900... get the 90 for 4v pre outs and ipod cable

Great tip - thanks

Beware buying off ebay, Pioneer has no authorized dealers on ebay and will not give warrenty coverage to any Pioneer products purchased on ebay.

90 and 900 i dont believe have any signifcant difference. i researched on all models before buying my 900 i ended up getting. pricewise i got a 900 a couple of bucks cheaper then a 90 choice is your my friend

90 comes with the ipod cable(normally $50), 4V preouts(vs 2.2V), and an extra year of warranty if bought from a legit dealer
