Just adding another data point for the Puma. I've used mine heavily for the past 6 years and I really like it. No issues at all, and plenty of air when I need it. I lived in Wyoming for w while on a remote ranch. I was airing up and down every time I left the ranch. I also run some tools and airlockers with it. I separated the pump from the tank, and mounted them in different locations, because that worked out better for me.
