In the shed:
5 yr. old Karcher gas pressure washer w/4hp Honda-It starts on the first pull every time. Came with a half dozen different tips for different applications, including a vehicle soap foam tip.
10 yr. old Graco Nova 300 series short frame, airless paint sprayer--it has made me 20x what I paid for it. I did have to rebuild the pump, once. I was handed an unmarked gallon of military paint and used it to spray some military vehicle sideboards for a friend. There was no thinner I could get into the sprayer fast enough, not to clog the hose and pump. Lesson learned.
