I'm still the proud owner of a Nikon FM, which I bought new 27 years ago. I would like to up grade to a Digital SLR. I'm thinking of the Canon 10D.
The issues are these, will you get comparable enlargements to 10x8, yes, will you notice the difference in comparing film to digital, not readily. You will have to do more computer work, but you will get more out of your images. I used to hate shooting with film, thinking I had great technically exposed shots only to find I had great compostion, who's expouseure was not always spot on.

I have a Nikon Coolpix 995, which I have had for 2 years, it has done more to reinvigorate my photography than anything else. I love the digital aspect, I have an enlargement I had professionally printed on a large Epson printer, 20"x16" from a 3.3mp coolpix camera, it is as sharp as I want it. So I'm just about to jump to the SLR,for more flexibility. I'm sure 6mp is enough for me, if it is out of date in 5 years, then I guess I divide the cost by 5 years & that is what my entertainment cost me, along with the thousands of photo's I would have.

With my Nikon Coolpix I have taken 2000 pictures in 2 years & it seems I hardly use it!

I like the Pentax very much, I have always wanted to try Canon so that's why I'm going that route, also they have a great choice of vibration control lens'es which appeals to me.
