Printing at home is v. expensive and as already mentioned longevity of prints is questionable. My solution - I'm happy to keep most of my pics saved on pc and backed up to cd or dvd, but for those you definately want a hard copy of, save to 'for printing' folder and keep an eye out for special offers. during the summer boots had a special - 50 prints for a fiver! Got 350 pics printed for £35. Won't suit everyone but works for me.
BRL - Good buy, also just bought a 256mb card for about 30 quid (ebuyer.co.uk, they have some real bargains)
