I was initially going to go with Pentax a couple of years back but they are just not available anywhere (digital). Olympus were available in a few shops whose owners understood why people went for them - but alas even they don't stock them anymore.
When my E520 gives up the ghost I'll have to regrettably go with Canikon. I hate following crowds though
m4/3 is starting to look like a viable option for me - I'll wait for some nicer bodies
