Got the 630w Type M here in the missus' rig, I got it at the beginning of 2007 iirc, and got knows how many different rigs of mine that thing powered, it's been quite a few anyway, and it's still going strong, running an o/ced i7 and 8800GTX...
I wouldn't go around recommending them, mostly because of all the issues other guys have had, however, I'm pretty sure that it was only the 530 or 580w Type R's that were dodgy.
I had to open mine a couple months back to clean out all the years of dust that built up inside it, and the innards looked like what you'd expect to see in a high quality PSU, it looks very well built tbh.
They are pretty decent PSU's imo, that don't cost an arm and a leg.
