There’s this one also. I do own one of these, and have had a lot of luck with it. A little less horsepower than the flying pig. But I can still get my springers dry with it. I haven’t had any trouble w the switch on my shernbao. I had a chris Christiansen dryer, that had the twisty knob velocity adjustment (similar to fly pigs knob) — the knob broke. Honestly, thinking about that I’d go w the shernbao because of that! I like the dial better than the knob!
