The OP asked "Am I getting a Good Deal?" Sorry, but asking that question on this forum is an absolute waste of time. As the OP can see all you are going to get is post after post of how this rig is better and no matter what the price is, they know you can get a better deal. If these forum members had been negotiating when the Dutch bought Manhattan from the Indians, they surely could have gotten it for 15 beads instead of twenty. No way would Jefferson have had to pay $15 million for the Louisiana Purchase and Seward could have easily bought Alaska for half of the 7 million dollar purchase price, and probably gotten Siberia tossed in as a kicker.
I don't know the specifics of the rig the OP is looking at. But if they have done some basic research into pricing similar units and the price is in line and the rig is the floorplan and size they are looking for, they should feel confident in purchasing it and enjoying it. If their catalyst for a purchase is a consensus from the members of this forum that they are getting a good rig at a good price, they are never going to buy.
