Depending on how much you want to use it, the inexpensive ones available at a place like Wally World can do a great job. If you're only gonna do your truck, you won't be putting many hours on it and it will last a long time. 1500 psi would be plenty to do a good job. I have a cheap-o 1500 psi unit, Coleman I think, from when my son was involved in amateur motocross and it did a great job of getting gobs of mud off the bike. For more extensive use, such as Dynamite talked about, you may want to look at a more expensive unit.

As far as the truck, I've never used it. I'm with Broom on this one, I just don't want to be bothered with it when I'm home. The Beacon does an excellent job of keeping the engine and under carriage looking like new, and it's hard to fight the sirens song of the big screen, an incredibly comfortable couch and a cold and frosty beverage!
