Should I buy a 50gal spray rig that has a electric pump and 300ft hose. It is sub $500. The guy said he has not used it in a year and a half. I will be checking it out tomorrow. What should I look for and test out. Is it still a good deal if the pump doesn't work. Can it be rebuild or clean it. This would be my first rig and I think its better than paying 4000 for right now. I also needs a spray gun. Im thinking I would buy a 100 or 150gal tank and spray gun, and come in under $1000. Also do you think the hose will be ok after sitting?
