I've had real good luck with Best buy for the last couple of years usually buy online with free shipping. Good service after the sale both online and in store.
bought a couple of Hp desktops and a gateway laptop from them.
I buy online so I don't have to wait in line and deal with the teenage salesman at the store, they usually don't know any more than I do but they are convinced they do.
