I've long been a fan of HP products, having owned four over the years. Current machine is an HP psc 950 'All-in-One', an earlier model similar to the HP2175, and it has been excellent.
My only reservation about HP's current models concerns the capacity of the ink cartridges - now typically only about 17ml. Cartridges for earlier HP printers hold about 40ml of ink, but cost about the same.
