I have a Generac pressure washer. Does anyone know where I can get a flexible hose for the wand (lance) like the ones at the coin operated self serve car washes? The long solid one that came with it is great for most stuff, but a flexible one is better for getting under vehicle fender wells and some other tight places. I checked the Generac manual and web site and didn't see one there. Lowes doesn't have any either. I've also checked paint stores, hose and fitting supply stores, etc. Does anybody know where the coin operated self serve car wash owners get their stuff?

PS: I saw this one at Northern Tool and it's a bit pricey at $60!
