OK, so my Pronto TS1000 has finally given up the ghost; so what about a replacement?

To be honest it was way more capable than I needed but the one thing I will really miss is the strength of the IR signal. I currently have all of my equipment in the rear corner of the room and I can happily point the remote anywhere towards the TV and it will bounce off the wall to the equipment, a total distance of over 30ft.
Apart from the signal strength my only real reqts are that it is a wand rather than a tablet, controls at least 4 devices, and supports some basic macros (mainly to power everything on and off).

Initially I was looking at the Harmony 300/600/650, probably prefering the ability to name my own devices of the 600/650; however, reading several reports on the poor IR strength of the more expensive Harmony One has put me off.

So, am I right to steer clear of the Harmonies? Any other suggestions?
