Yikes... I'm not trying to be mean, and I respect your right to ask whatever you think your set up is worth, but I would highly suggest deleting or editing your last post. Many of the business you plan on "ripping off" do a lot of business here on the forum. In addition, I think you would get less from a business than from a private sale, seeing as they have overhead and need to sell something for a profit. In addition, since all of your equipment is used, they would not be able to offer a warranty on said used equipment, which would cause many to hesitate to buy from a business.
In past instances, it has been far more profitable, and quicker turning, to part out a set up. Those that commented before (myself included) mean no disrespect, but we've been around long enough to see how it goes on here and on craigslist.
Good luck with your sale, however you decide to proceed!
