Just a reminder for everyone that there is typically a difference between asking price on eBay which literally can be anything, and the actual sales history. When doing eBay price research, the best option is to check the "Sold Listings". This way you avoid only seeing asking prices, or completed listing that never sold. For rare products this is less useful, but typically this approach provides the most realistic market price.
Something else to typically consider is that eBay also typically warrants a higher sales price than other methods of sales due to the customer base you reach and the fees involved. It's much more likely to sell something $100 higher when you have millions of potential customers and buyer protection, compared to thousands of customers with little buyer protection.
Awesome unit though and good luck with the sale!
