I never did buy the IC-7300. I ended up finding a mint IC-7600 and it won me over. While the IC-7300 is an awesome rig (I'm pretty certain prcguy will agree ), but I really like the larger form factor of the 7600, and it also is an awesome rig. I sold my 35A power supply and purchased a 12A power supply which is more than enough to handle the 2.5~3A's is needs for receive only.
One caveat...let's assume money is not an issue for the purpose of this question.
