Yup, its great, also the ptr08060 is a great one too, its just like the 8100 but rated at 6amp instead of 10, which is still plenty! I haven't found anything better.... they are all I use anymore as well!

Yep, the PTR08100W regulator works better than any other regulator I have used....runs cool and the efficiency is wonderful...it is now the only regulator I use....if there is something better out there I would like to know about it.....
Building mods is a hobby so I'm always looking for "better" and "smaller"......and the hard one to find is " a small digital voltage display", which I have not found yet......
