Selling an NES.. Fickle hardware

[SuperSonic7]

Afraid of dealing with blowback if the buyer has problems with it from dirty carts. I did disable the lock out chip to help this problem but still. Also, what is a fair price for one in decent condition, a controller and RF connecter, after market power supply? I see they go for about 50 shipped on ebay.

I usually sell them on forums for $40 to $45 depending on condition with original power supplies, so I'd say about $40.
