The less featured ones are going for $25 shipped on Ebay.
There are a few plus model docks on Ebay for $25 + shipping.
Even if I were selling one, I wouldn't let it go for that little, considering that the plus docs are around $150 even with my corporate account. The normal price is $180.
might be helpful if you include picture, i've one not sure if it fits, model # or something will be helpful. i've one i'll check if it's what you're looking for, send you PM later today (more likely tonight around 8 pm or so)
