I see very little mention of Shelden Sporting goods in Kansas here except in very old posts. For those of you looking to buy a compressor, you should really call him up and see if he has anything available. I was just reading on some scuba boards and he recently sold a 4.2 SCFM kidde without filter/assembly for 950 dollars after he went through it. Customer had traded it in, just needed reed valve cleaned and everything else was perfect. Shelden builds/services them and other compressors and has a stellar reputation in the diving community. You could have added a couple hundred for a real filter to be added, and after shipping had a real compressor that would last a lifetime for under 1500. Shelden spends most of his time on scuba boards, he is a former navy demolitions diver. I have one of his last 2.2 SCFM compressors before his supply of them to rebuild ran out and it has been perfect since 2015. Just change oil, inspect/clean filter housing every 40 hours or every year whichever comes first. I just this year finally repacked the filter for no other reason that it has been close to 7 years. I keep reading about all the cheap compressors people get and the littany of problems with them. If you are looking for a good compressor, give him a call. You never know when he might have one and get lucky.
