Query: Replacement Parts prohibitively expensive

I purchased this unit from a big box retailer in Nov. of 2007 for $220 and, while the service has been acceptable it has become necessary to replace some leaky parts. At first I said to myself, "Self, this is a clever design" The hose and spray assembly was modular such that they could be replaced in a 'plug and play' fashion. I was stunned to find that the retail price to do so would have set me back $180.00!! Clever indeed!Research on the net has got the price down to $135. but that's still too high in my opinion. As an engineer, I am capable of rebuilding the unit and that's what I'll be doing (parts are about $40.00) but offer fair warning to those who are not as mechanically inclined. As such, I'll be purchasing something different next time.
