Regarding Wayne's points. Compared to the KXPA100, the RM Italy 150v (lots of used ones available for $150) doesn't have 6 meters, has loud fans & relays, suffers from diminishing power output on the bands above 20 meters and the IMD performance isn't acceptable unless used in the low power setting. I think it is qutie obvious that, despite the cost, the KXPA100 is a much better piece of equipment. I'd love to replace my boat anchor with the KXPA100 but I just spent my spare ham funds on my wife's birthday present this morning. Maybe another day.
