I have used the Master air compressors for several years. You can buy through Amazon from TCP and get a 5 year warranty. I just upgraded my tankless model, after about 4 years usage to the new tank model:
I have had it a couple of months and it is a big improvement over the tankless model. Very smooth, quiet and it is nice having the motor only run occasionally to refill the tank. Not too expensive at $140 with free shipping, (Prime member).
Cheers,
