Hi all, my old system has died, lasted a good 8 years, but, it's now no more, I've been talking to a guy who sells the Technomate systems and he tells me the Nano 2 is the better box from the their range, I've racked my brains over which one to get but, cannot make up my mind, there's the TM Twin, the TM 5402, who is the Nano 2 the better box, or is it?

Help please.
