yeah a belt driven pump is the best for me too. I hate listening to a oil/belt less compressor. Plus I am not sure about their longevity
I noticed harbor freight is now selling "quiet" oil-less compressors, would be interesting to see how much quieter they are.
Neither here nor there I suppose, but the only time I'd see one of those not working so great for me is if/when I need to plasma cut again and air demand is for longer periods of time.
I used to use an air cutoff wheel quite a bit, but all the electric tools I have just seem a lot easier to use in most situations now. I basically have a 60 gallon tire inflator. Lol
