I would suggest BunnyMilk, he makes pretty stellar elctro-rock-soul music.
But yeah, if you say "I want some electronica bands here is what I have so far - Depeche Mode." I don't think it is electronica that you are looking for! Also ignore everyone elses opinion because they are wrong. Especially the person who suggested "Peaches," because Peaches is probably the worst human being ever invented by god.
BoC is kind of hard to digest the first time round. If you haven't really been weaned onto electronica by some offshoot of the genre and you stuck in a Boards album it would probably psyche you out a little bit. I am huge Boards fan but even I didn't like it the first time I heard it. I tell you what it was that really put me onto the Boards though and it is something that I suggest everyone does. Flick your TV over to Discovery Central and watch one of those nature shows. Not the shitty ones like Ray Mears. I mean the PROPER ATTENBOROUGH NATURE SHOWS WITH AMAZING SHOTS OF NATURE AND ANIMALS AND STUFF. Mute the volume and stick on a Boards Album... It is probably one of the most fantastic things you could ever do. Also watch the music video for
Dayvan Cowboy. It is beautiful.
Amon Tobin is fantastic but all of his albums are seriously different so I think it would be pretty hard for anyone to say CHECK OUT AMON TOBIN and leave it at that. Whatever Album you listen to is considerably different from whatever material you don't listen to. If you are going to check it out I would say start at the beginning. Cujo - Adventures in Foam or Bricolage. If you enjoy these albums you will enjoy Tobin, but if you jump in at the Foley Room it's a lot harder to work backwards.
Massive Attack. This is not electronica, everyone is telling you lies. As fantastic as it is though they are only trying to say HEY I LIKE MASSIVE ATTACK I AM COOL YOU SHOULD LIKE MY MUSIC TASTE.
Daft Punk is a tricky one but probably the closest thing to DEPECHE MODE that you would find on any of the lists people are giving you. It's pretty Techno but it's a lot more down tempo techno. Also be warned that Daft Punk have made a lot of shit music. You're best picking up a best of album or something to see if you like it. Or just listen to "Harder, Better, Faster, Stronger" which is the song everyone loves. (I am quite partial to Robot Rock myself though.
This is just my opinion on some of the artists that people have already suggested to you. I am not going to give you a list of bands that I think you would like because a lot of them have already been suggested.
If you are just trying to get into electronica I would avoid Aphex Twin and the Chemical Brothers though. They are both absolutely fantastic don't get me wrong but I don't think it's real EASE YOU INTO THE GENRE stuff.
