Good price for used HS1850?

[foililm]

I saw a used 1850 (not the A+) for sale on Real for $550 plus tax. I didn't pull the trigger and it's gone now, but does that seem like a fair price? I am on the look out if anyone is considering selling theirs...

400-550 seams fair. At least that is what I've seen.
