While a gas compressor may be more vesatile they have to many drawbacks in my opinion. I always recommend the electric models when ever possible. Electric models are much quieter, have less vibration, less maintenence requirements and no worries about Carbon Monoxide. With the ALKIN electric models you can carry on a normal conversation while filling tanks.
I sell about 10 electric models for every gas powered model. Most of the gas powered models have the Honda motors but I have one in stock with the new Entec Briggs & Stratton motor on it. I like it better than the Hondas now, starts first pull almost every time. Both the Honda and the Briggs are very loud, I can not tell any difference there.
If you do decide to go with a gas powered model go to Home Depot and get a intake hose assembly to get the fresh air intake as far away as possible from the exhaust. I include them on all my gas powered breathing air compressors. Change your purifier cartridges like clockwork when required. You should do that anyway but of course more critical with the gas models (all brands)
In the long run the electric models are more cost effective and safer in my opinion. Best Regards, Curly
