I just ordered a Canon 30d -- I'm hoping it's worth every penny because it's quite a mound of them. I'm trying to take my cycling photography to the next level and -- even though I'm not quite ready for it -- the 30d should alleviate some of my gripes with the Rebel 300D (hard to tell if things are in focus with viewfinder, can't activate AI servo independently, slow startup, low fps, etc...). Although I was jealous to see one of my co-workers with the Canon 5d, the 30d should actually be a better for action photography.
In other action photography news, as of Tuesday that wonderful blow-up-stuff show now has the rights to some of my photos for their Web site. Irony is delicious.
