Film vs. Digital

Lately I've been taking lots of photos with my Pentax k1000 (see my photo's from Chefchaouen below) and even though I love the camera, it's getting quite expensive to develop and buy so much film.  I would love to start posting more pictures of my day to day activities so I'm looking to buy a digital.... Any ideas of where I should start?
Some models I am considering:
Canon EOS 5d
Leica D-Lux 4
Nikon D90

There's a huge price range here as I've still got a lot of research to do. I haven't really decided whether I'm going to go with a compact camera or an SLR. It's all too confusing. Sorry about the bad scans. I don't have time or the patience to re-scan and remove the lines!

Barcelona

I've just gotten back from a trip to Spain and Morocco. I fell in love with Barcelona and would like to live there some day. I miss the food already! We arrived at the end of winter and the weather was perfect. Here are some shots I took on my travels.
