I just recieved the HK TC1000 remote today after ordering it last week. As soon as I got home I programed my living room system in and tested it out. All codes were built in with the exception of my B&K Ref 20 proc. and a few buttons on my Panasonic DVD. However, learning the new codes was straight forward and easy, especially with the software. Once I had the devices loaded, I tested them out with my system and found the range to be superior to my RC2000. I tested it from my normal listening position of a straight shot of about 14 feet; no problems. I then moved approximately 20'-25' away and at angles up to around 40-50 degrees off center; again no problems found.
I am not going to sit here and jerk anyone's chain and say this is better than the Pronto; I haven't tried that unit. I'm sure that unit is an excellent unit. However, I went with the HK because the software came with it, and there were no promises of software ever coming out for the Pronto. Luckily for me though, I found this site after I ordered the remote, and was not influenced from the negative posts. I do have one minor complaint, I can't seem to arrange the device buttons, only the activity buttons. Not a big deal since you can make several activity screens for each device.
Just wanted to throw in my 2 cents on this product.
