I really miss many of ML capabilities, including Intervalometer and enhanced Bulb.
Have you checked CHDK?
Thanks for the suggestion. I'd been barely aware of CHDK, and ignorant that it had anything to do with Canon point-and-shoots.
I've gotten it installed on my S110, and starting to get up to speed on it ... and it definitely has intervalometer capabilities, along with much more.
By looking at CHDK for S110, I discovered the hack for 400D. Thanks !
