I was on a long search for compressors, I had Pari Pro-nebs get slower and slower over just a couple years. I think we need a serious compressor for the 1-2 hour+ per day we run it. The Devilbiss Pulmo Aide 5650 seemed to have good reviews saying it lasted over 10 years w/ no issues. So far it's been good for me, same compressor model I had 15-20 years ago, I realized I don't have a need for really compact ones that get super-hot and break down over time.
