"Antennas, etc are a separate issue"
Antennas are, well, the most important thing. If I had that much land.... well,
A lot of suggestions were made, but there really isn't enough information on your operating preferences to give you good suggestions. If you haven't quite figured out what you plan to do on the HF bands, the Icom IC-718 is an inexpensive starting point, and resells well if it doesn't meet your needs.
I always say, you can never go wrong with an Elecraft K3
but that is a little out of your price range.
