How much for a used Kitchen Aid mixer?

[Bernadine]

I think I'm going to go ahead and sell mine.  Xh bought it for me, and I rarely use it.  Actually, I haven't used it since I left him.  It's just such a hassle to pull in and out of the cabinets, and it takes up too much space.  How much should I ask for it?

I'd ask for $50 and let it go for $40.

I would probably go $75.

Which model? Any accessories? If it's in like-new condition, I'd start with 1/2 off of retail.

ETA:  by "retail" I mean what you would actually pay for it at a store, not the ridiculous "regular price" (which NO ONE pays!)
