Can anyone suggest the best spray gun to buy for me to use as a mobile business. I am about to start a days training with Sienna X, but am on a budget, I was going to use the sienna tanning products, but was hoping I could buy the spray gun and tent in another make to save some money. I have been looking at hvpl pro compact from sunless solutions and wondered if any of you have had any idea how this is as an alternative, or other suggestions?
