Well, it sounds to me that you did not pay enough on the shipping, so, Doomy did not ship the Amiga 2000 until you mailed him the needed funds for shipping. I do not think that he had any intention of ripping you off, because you did get the Amiga 2000, but only after you mailed him the correct amount for shipping. It sounds like you are very happy with your purchase. So, why spread negative feedback about Doomy? He did not do anything wrong. I think that the guy is getting a bad rep for no good reason and many people here on Amiga Org think so too, but are afraid to speak up for fear of getting kicked off the forum.
George, (so again, you have clearly identified yourself with the comments made) you damn well know that the price of the unit and the cost of shipping was all explicitly stated at the close of the auction. Only afterwards did you change the terms of the sale. Only after me not receiving the unit for an extended period of time and only after I sent correspondence to you did any action on your part occur.
...and I gotta tell you, if telling fact is considered negative feedback and as a result all that happened is that your feelings are hurt, then you should consider yourself lucky.
By the way, the videos are great, keep up the good work! They keep me entertained for hours in a "Silence of the Lambs" kind of way.
