I'm trying to decide whether to get a 10D/20D or new lenses. Currently I have an Elan 7 35mm with a Canon 28-90 USM and Tamron 75-300 lens. Since I can't afford a DSLR and new lenses right now, I'm trying to decide which would be the more practicle choice.

I really like digital photography. I like being able to have my pictures on a computer where I can print what I need rather than having tons of prints laying around. Digital allows for cheap practicing and I like getting instant feedback to see what I'm doing right or wrong....however...

I would really like to start upgrading to canon "L" glass and/or Sigma "EX" glass. I kind of feel that the longer I stay with 35mm, the more money I'm going to be spending in the long run. I know that with my little A75, I don't hesitate one bit to snap away, but with film I don't take nearly as many pictures because of film and processing costs.

Any advice?
