I've had one for 4 weeks now - what a great unit. Bought on eBay (US) for 1/2 the price they were wanting down here, and secondhand to boot. Before it arrived I downlaoded all the manuals, latest firmware etc. etc. and once it arrived had it programmed in around 4 hours. Keeping the ccf file on a pc makes changes so much easier, just do the changes, dowload to the unit, test and repeat if necessary until you've go it right. Making changes is an absolute breeze once you get the hang of the programmming, layouts etc. and with RemoteCentral there are heaps of layouts, codes, help etc that make owning one of these even easier.
I got it setup with bitmaps for station logos, macros to perform device changes according to what you want to watch (TV,DVD, Tuner)
Can't live without it now
