Wagner power painters...?

IVE USED A WAGNER. there not terrible it was on sale so i did not pay full price paid bout half the price bout 56bucks. my grandma owns a 19teens Victorian and i am painting it as weather permits . the Wagner power sprayer isn't bad for painting but u have to make sure u clean it throughly with mineral spirits ,Ive shot oil and latex through it and it still works great there easy to take apart but the holding capacity kinda blows. mines the corded i could hook a hose up to a 5gal bucket but those buckets are like over 100bucks and i may not even need that much
