As soon as I go back to the USA I will get one. I use my FT857D as my portable radio, and my current 100W backup rig. I am keeping the 1500 for transverter work (plus being able to run SmartSDR and PowerSDR simultaneously is great).
But the TS-2000 seems to me the perfect backup radio. it covers everything. You can work satellites with it, even add 23cm, and do HF work in a pinch, with internal ATU.
Great CAT software and possibility to work remotely with the kenwood made smaller front end.
Now... I have never used one, but it is my current choice as backup.
A better, more modern quality DSP, HF-VHF-UHF backup rig, would be the Icom IC-9100. But it is also well over double the price of the kenwood. Before I spend the money on the Icom I would upgrade my Flex 6300 to a 6700.
Icom pro3 is main back up now since I bought the flex 6300. Still have icom 7400 (746 pro) which was my original backup and 6m radio, but now it mainly works on 2m ssb/cw. ft1000d and ts590s both were sold last year due to age of the former and its poorer performance on ssb compared to 6300, and the latter sold on due to its alc overshoot. I mainly use the pro3 on a daily basis to transvert onto 4m from 10m and to switch to from the 6300 to remind myself what a great radio rx the 6300 has on lf and crowded ssb conditions :-) The pro3 is up for sale as I plan to buy a higher spec 4m transverter to hang off the 6300.
