I have never bought a pressure washer from them but many have and had good luck with them. I would suggest finding out just which unit your looking at then ask about that one.
My suggestion would to always give your local dealer first crack at service and sales but that does not mean you have to buy from him, only if his prices are in line with others OR for some reason you feel you would rather deal locally.
As the others have stated there are many good companies out there to deal with.
What I would ask before buying from any of them.
Shipping cost, is it true cost or inflated, some do inflate that cost pretty high.
Warranty, how long, who pays to ship item back to them or to the factory? Or do they allow local dealer to repair and pay for it?
How long a wait for replacement or repair, there is one company that takes months to authorize repairs to be done. Others are right on it.
When ordering is there a dollar amount you must order?
Again how about free shipping if over a certain amount of money
