Reply To: Shoebox vs booster?
The Shoebox is very easy to work on and the parts are inexpensive. Not sure the same could be said for those boosters. You can use even the smallest shop compressors as long as they have a tank. I have the smallest Senco model. About $100. works great! If you keep the Shoebox properly lubed and keep the belt tight should have no problems. The compression cylinder o-rings will have to be replaced at some point. but its not hard and they have videos on their site on how to do it.
Also it looks like you will need more parts to make the booster work. Air fittings bleed valve maybe make a stand or mount for it. The Shoebox is designed for this purpose. The only thing extra that is recommended is a moisture filter on the input line.
