Rob, I have sold just about all of my modern stuff in the past couple of years. With the exception of one botched transaction for Ep I stuff, everything went pretty smooth.
I divided all my stuff into lines, POTF2, Ep I, POTJ, and Saga. The Saga went first when I was selling followed by POTJ, POTF2, and Ep I, which I still have now. I sold all of the stuff on eBay, knowing I wouldn't get all my money back, but happy to get something for it and get it out of my house. If you want to sell fastest, put an entire line on ebay with a decent BIN and you may get some people to bite.
Otherwise, I suggest do as someone else (Bill maybe?) suggested and divide the stuff into lots of 10-20 or just donate some of them to a kids program for Christmas. I'll be donating much of my Ep I to the Marine Corps Toys for Tots.
