I have a telescope that I may be in the market to sell in the near future and am wondering if there is a good source to find its value in the used market. Although it's never been out of the box, it was given as a gift nearly 10 years ago and I have no idea what it might be worth. It's a Meade 114EQ-DH and I see a few on eBay that look similar but none that are in-box and in brand new condition. Is there a source of prices similar to a blue book for cars?

There is a telescope blue book web site, but it's more for high-end telescopes: http://www.telescopebluebook.com/
Unfortunately, 114mm reflectors like yours are a dime a dozen and have almost no resale value. They are typical "department store junk telescopes."
The classified section of cloudynights.com is extensive enough to be very useful for determining the market value of components.
