Why do you specifically want an electric sprayer? Fed up of pumping a handle up and down all day long?
Me too :
You could consider an alternative such as an inline injection sprayer. I've just ordered one off eBay, about half the price of UK suppliers even with the delivery!
check this eBay shop out:

When i get my sprayer, hopefully early next week, I'll let you know what I think of it
