All sound advice. We are lucky enough to have a really good independent guy just down the road apiece in rural Devon (UK) who puts together systems that do just as much as you want, provides tech support and advice ad lib, and (O joy of joys) buys back your older computer or printer in part exchange! So we never feel that we have invested in immediately obsolete technology. It also means that things do what we want them to and not what the multiple retailers think we ought to want.
