Macintosh 128K - what's it worth?

I've got an original Macintosh 128K, bought it brand new myself in 1984. SN is F4281SXM0001, which, according to another thread, decodes as;

F = It was made in Freemont CA.
4 = It was made in 1984
28 = It was made in week 28
1SX = Is the sequence number
M0001 = Is the model number

All the original disks and manuals, MacWrite/MacPaint etc... MSWord, MSBasic, imagewriter cable, appletalk network and cables. I just plugged it in an played a game of Sargon (chess) and lost, so it seems to be working well. The internal disk, 400K I think, has a hitch is it's get along, so you need a paperclip to assist in the eject. It's got an external 800K drive as well. Some of the floppies are corrupt, it's only been 20 years!

What would a guy ask for it if he wanted to sell it, and where would he go to do that (other than eBay)?

Thanks for the input. I do not have the original box. I do have the original MacWrite manual and most of the original disks, however I'm not sure the data has any integrity. The case is in great shape, one small ding on the front but other than that it's nearly perfect. A little age'd in color, but not the ugly dark yellow that you see so often.

Any ideas on what it's worth, I have no clue ($5 or $5000)? And where would I go to sell it?
