Thinking about selling my prius, what's it worth?

I recently purchased an 07 prius and love it, but I may have to sell it. I got excited and bought it before I sold my old car, an 06 Accord. Now I can’t seem to sell the Honda and the 2 payments aren’t much fun. Can I get some feedback on a sales price that I should ask for? If anyone is interested in the Honda, let me know!

Not sure which package it is, but I will list all the details.
2007 non-touring prius with 1500 miles
Nav system – voice activated
Hid lights
Fog lights (wow they really don’t work so well)
Smart key
Backup camera
Bluetooth
6disc in dash cd
Stability control
Security system that I have no idea how to use
Auto dimming rear view with home link garage opener
Jbl stereo with 9 speakers
Satellite radio, xm
beige cloth interior, gold exterior
perfect condition

The web sites weren't much help, nada said insufficient data, the latest year that I could look up on kbb was an 06 for $22,260. Edmunds said $21,500, but they didn't have a place to add options, so i am guessing that this price is for a striped model. Any more suggestions?
