for 559 this one looks pretty good:
2500 PSI, 2.3 GPM and 5.0 HP
Motor: Gasoline Honda GC160
Pump: Comet (5 year warranty)
5750 Cleaning Units
Chemical Injector
Black Powder Coated Frame
10" Tubed Pneumatic Tires
Trigger Gun and 36" Insulated Wand
4 Spray Nozzles - 0? 15? 25? 40?
25 FT of Pressure Hose w/QC connector
Direct Drive
Weight: 80 lbs

Little light on PSI and GPM, but might work for us. I'm a BIG fan of warranties <img src="/forums/images/graemlins/lol.gif" alt="" />
