9833 in like new or new cond would probably be up to 200.
more like 150 for a used one in good cond, i think i've seen them go around that.
with the issues there is, i don't even know...

also i've seen some in for sale, haven't checked the price.

mp3 has been slow as hell on my alpines back in the day too, 9835/9853. so it's not an issue per se.
