I’ve got two. One is an old industrial clamshell type. It works well but it can leak some. I bought a medium size Scat from in a package deal in a big buy. I like it but it’s not near big enough for big items. Get the biggest you can afford. You will use it all the time. Get a big compressor and a good water filter trap. I use the one with the paper roll from TP. They are a great source for parts. I use a regular big shop vac with bags for one. The bags for the canister type can blow out and send dus5 all over the place.
