I have had some experience with a couple of sizes of the Itchy Hichy-baracus , Inc ( IHI) , or how ever you say it , they didn't have many problems , the two worst problems I had to deal with was resealing a swivel joint and a controll valve spool , parts where the problem the seal kit for the swivel took two and 1/2 months to get flown in next day air , they ran well and I know of one that is still around even after taking a dunk in 12 ft of flood water , I did find them a little under power as compared to a machine it's size , parts would be the biggest problem I would see
