i think it also should be mentioned that almost all the manufacturers will let you upgrade to a higher end machine. that is, take your machine back and give you credit toward a higher end one. what they do is bring your used one up to snuff and resell as reconditioned, but i don't know if you can use your credit toward a reconditioned one. you might have to put it toward a brand new one only. still it's something to think about for the future. you should certainly ask.
