I paid $130 for mine 5 year ago used on ebay but it's still in perfect condition. Great cd player! I use it on my tesy bench now. I like it better than any of the higher end alpines they made during that time-I've owned them all and they were way to complicated. This unit is straight foward and sounds awesome.
I think I paid like $75 for mine in near mint condition off eBay about a year ago. It's a pretty decent unit, but there's really nothing to it other than 4 volt pre outs. I've also got a 9827 that I'm letting my cousin use in his car. That was in mint condition until he wore out the lettering on the buttons. I'm thinking I can switch the buttons from the 9807 (which doesn't work well anymore) with the 9827 to get that "mint" look again. They're identical units, just a different year.
