Value of my NES?

I have an NES that I would like to sell/trade. I'm not trying to sell it here. I just don't know how much it would be worth. Maybe some of my fellow CAG-ers can help me out.

The NES and accessories are in phenomenal shape. They haven't got a scuff or scratch on them. Obviously, they're not "new", but pretty close. I'd guess that they were only used once or twice and then put away. This particular combo has:

NES
Power Pad
2 controllers
1 Zapper Gun
All the OEM cables

Oddly enough, there isn't a cartridge with it. I could order one, but I'm not sure how much more it would increase the value. Any ideas on this, too, would be appreciated.

I can post pictures if necessary. Any input on this is greatly appreciated.

Sold mine before Christmas for $70 but I had 4 games, 2 controllers and red gun.

Goto Ebay, click Advanced (to the right of search), click Complete Listings (below search), enter search term and compare. http://www.ebay.com/sch/ebayadvsearch/?rt=nc

If it's a low serial number it could be worth a little more. Do you have any of the original boxes or manuals, etc?

I think less than$40 cash online maybe $50 but u will be chargd fees and shipping will be like $15

maybe 50 bucks on craigslist. The box is worth abit though. I sold my mint box last year for $100 on craigslist. Had multiple people looking for it to.

Box can double volue twice

If you need to sell quickly then of course use CL or eBay, but beware of people trying to lowball on CL. If anyone is interested in old skool consoles, check my stuff that is selling: http://www.cheapassgamer.com/forums/showthread.php?t=336448
