my local supplier just started stocking these
basically claims to be like a M2 (but better).
has auto start up and the usual shutdown controllers on low voltage.
the one i have works fine, survives crank no probs.
the power off options , for how long it holds the psu in "soft" off mode before it kills the power to it can be changed while its running which is nice, so 45 seconds after i shut down the psu is turned off, so no power draw.. then when i turn the key.. its away again auto starting.
has amp turn on as well
this is the manufacturer
