"The Prep/Master 3038 is a machine that has a reputation for being a very productive and reliable piece of equipment."

"Upon receiving the machine, we had our sign company create and install some decals on the unit. Then we then sent it to our professional photographer for a photo shoot."

"We felt that it was important for us to have quality images we can use to show our clients as we discuss our increased prepping capabilities."
