Great sprayer, I purchased the piston rebuild kit here on Amazon (Solo 0610407-K Piston Sprayer Pump Repair Kit) and the wand rebuild kit (Solo 0610411-K Sprayer Wand/Shut-off Valve Repair Kit) even if I did not rebuild this sprayer, I feel I have gotten plenty of value from this unit, and would not have a problem purchasing a new one. I do believe "Solo" is a German company...hence the quality.
