I have a Whistler radar detector, model 1785 on eBay right now. Great condition, there's a description on the auction page.
Also, I have a 15 inch subwoofer and enclosure in very good condition. It is the Fatboy 2 made by Crunch USA, 800watt. Take a look, lemme know if anyone's interested. $50 obo. I'd prefer local to the NOVA / DC / MD area with this one.. pretty heavy.
