I have a 20D and I'm not tempted yet. I'm happy with the few shots I've printed at A3, I'm not really bothered about live view or shots per second and I'm not bothered about scene modes.
The anti dust technology tempts me and I keep wondering if FF may be the way to go, better high ISO performance would be nice too but right now I'm not in any rush to change and the 20D will do.
