Nothing intelligent to add as I use a big cobalt job I got for half price from lowes. It was around $200 and has been doing a great job for 7 or 8 years now. But, my question about a rusty tank failure that some say they are afraid of. I doubt there will be any 'explosion' or catastrophe in the event of a failure. I had an old sears job 40 years ago. The tank must have been made of very thin gauge steel. It didnt last too long but when it rusted through it was just a matter of a hole in the tank and no pressure. IF its not holding air how will it be pressurized enough to blow? Just a thought.
