I am a proud owner of an FT-817 since Green County Hamfest. Also considering the new KX-2 that Elecraft introduced at Dayton Hamvention. The cousin to the KX-2 is the KX-3, which has been out for a while.
M0JCQ put out an excellent comparison article between the FT-817ND and Elecraft KX-3. Not to be a spoiler, but both have their advantages and disadvantages, depending upon what you are looking to do.
