Here is a good looking model. With all the better insulation I probably will never miss the extra half ton, and the larger indoor coil and tx will basically add half a ton more. PLUS I can run this slightly over 60hz if need be.

Or here is one I might could get cheaper, but its for 410a. I could use 410a or just drain and flush the oil out. It would lower my BTU some more too though.
