I believe the IR pumps are now made in India (mine may be, for that matter). I know nothing about Puma brand compressors so I can't comment there. I can comment on the SS3L in general as I own one.
While it is now much less compressor than I need, it was more compressor than I had when I bought it used 8 years ago from a tire shop. If I was to guess, I'd say it has around 2,000 hours on it now. It has served me well, although it is getting ready to blow a head gasket. Shortly, I plan to remove the pump, check the head and pump for flatness, machine as-necessary and install a new gasket.
Other than the head gasket issue, it has been a good machine and I have had no issues with it. It is, however, a light-duty compressor and I suppose things like blown head gaskets are to be expected when they're run hard. Once I get my Quincy 5120 installed and plumbed the SS3L will become my backup unit.
All-in-all, I've made a lot of money with it and it has lasted many times longer than the oil-free unit I had before. With a little TLC I see no reason why it won't last another 15-20 years in backup duty before it needs a mechanical rebuild.
