My SRP-2100 has broke down. Started switching off/on repeatedly and smelling

That's the 3rd Topfield in a row, which started malfunctioning...
I love the Topfield receivers, and the add on programs, but these receivers have a very short life

So now - what should I buy as replacement ? My first thought is a new SRP-2100, but new receivers have been made since, and the SRP-2100 seems hard to find, so probably not so current anymore ?
Are any of the new receivers better ?
I need HD, HDMI and digital sound output. Record 2 HD and play another. Timeshift without first pressing record - all this I love in the TMS.
Should I consider one of the other models or a new TMS ?
I saw in another thread that the power supply was, but is no more available... Could it be the power supply ?
