I got the Subaru one from Costco last year, they should still have it (couldn't find it online). I think it was like $300. I'm really happy with it. I use it with my Torq foam cannon for car washing. But also for pressure washing driveways (it came with this cool attachment that makes cleaning driveways super easy)
