The $400.00 loader was a hard pass- - - -cobbled together out of three mismatched parts and a lot of angle iron. However, I did find a "good used" loader for $600.00 that only needs a few new hydraulic hoses and some patchwork on the bucket. I bought that one.
One consideration on any compressor is the volume of the tank- - - -bigger is usually better, as once pressure builds up to the cutoff point, it takes longer for the bigger tank to lose enough pressure for the motor to cycle back on. More resting time for the compressor and motor translates to longer life. I'm about to buy an "out of date" 200 gallon LP gas tank to be used as a reservoir for my compressor. $100.00!
