Hows the condition of it? I sold my slightly more abused one for around $70-80 (I think), and the other for about 100-120 (I can't remember exactly).
Keep in mind they didn't have the 901 connection, only 510
To be honest, those are the prices I bought them for. So I didn't try to make money for them. I sold them at or lower than what I paid.
Edit:
I sold mine for $75 and $106. The 106 was in much better condition. Both included priority mail and pp fees.
