As mentioned above....
This is an extremely rare and high-end item. As such, people are naturally leery of just sending some random guy over the internet $750. So... if you have the ability, I would highly HIGHLY suggest you try to snap a few decent-quality pictures of the unit (read: no cell-phone pics), more than likely with a white piece of paper showing your screen name and the date. This will at the very least show potential buyers that:
1. You do actually OWN the item and are not scamming with a product name only
2. Your item is in good condition and appears to have been well taken-care-of
3. You are serious enough about selling that you actually went to the trouble to spend 10 minutes (max) trying to attract buyers. Simply posting an ad on a forum doesn't really show this, unfortunately.
This is the customary method of selling on this forum, especially for relatively new users who have no or little feedback or reputation gained from selling to member of this or other forums in the past. I'd also suggest adding some info on how you expect payment, i.e., PayPal, money order, etc.
Just trying to help you out here a little bit, since this is indeed a nice unit, and I'd like to see you get a fair price out of it, while someone in turn gets a stellar piece of equipment. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
Good luck!
