both of the irivers i got off of ebay were in the 150-160 range shipped. they were the older ihp-120's (the black ones) and each had a LCD remote, case, ext mic, etc.
i have seen them go for less (cheapest was nickspick, picked up one for $75), and i have seen them go for more (180+s/h).
my first one was purchased thru an individual and it was pretty much flawless.
i just got my second one saturday and i am charging it up now... its not as nice looking as the first one, but it appears to have functionality and that it most important thing. this one was purchased thru a company that sells lots of electronic stuff
