ok, let's talk about running costs so ;o)

digital
what do i need to buy or replace regularly ? mmmm... may be capacity ? Pics took a lot of memory, but hard disk are cheaper than some years ago. about 150€ ?
What else ? if you are not lucky, a memory card lol (> 70€)
Printing a picture : i pay 25€ for a 40x50cm (excellent neutral and long life print)
And accessories, but it's not a must.
a new body after... 5-8-11 years ? difficult to say, but press say theses numbers
total : it depends on how much you print ;o)

classic
Regularly i need film of course (but you will take less pic in classic)
---> 2.1€/36 + 1€ develop. (i use 4 films by month, +-150 pictures)
i need revelator (7€ for 8 films), fixative(6.5€ for 30 films) and water (see it with your local water distributor lol)
Printing : it costs to me 6.5€ ton print a 40x50cm (if i'm lucky to do it correctly the first time lol)
a new body after ... 20-30 years ? my leica had 17yo and he is in perfect state.
total : +- 200€/year (it depends how much pic you take and print)

I repeat -> i don't defend classic or digital !!!!!! it's two way of photography, two ways of life ! Different and complementary  !!!
