I know what you mean about loving a film camera. But I will just add my two cents worth to your question to say, that you can learn photography a lot faster with a digital because you see your mistakes right away. You don`t have to wait for film to be developed. You can also just click away to your heart's content and not worry about running out of film (only space on your memory card

).
But whatever you are more comfortable with is the answer. If you want to improve more, I would recommend digital. If you are content with where you are with photography and with your film Canon, then that`s the thing to stick with.
As for suggestions on cameras... i would recommend checking dpreview.com
p.s. in digital photography you need a fairly good computer that will handle file sizes well, especially editing tasks.
Good luck !
