the only thing that bugs me on the han-01 is the limited commands (27 i think). the way i read it, to turn on a-1, that's one command; to turn off a-1, thats another command. thats two commands for one unit. the other item i was looking into but don't get the grasp of it is the OCELOT. well, i just ordered an ir543 off of ebay for 14.99 + 8 for shipping (brand new). i will let you all know if the new one works or if it's time to upgrade.
