I could not advise more strongly that you do not get a couple of manual flashes for your first flash(es). Get an ettl-II capable flash, whether canon or third party, so that you can use it on camera (other than fully manually).
I agree, and the OP did. (He ordered a 430EX II.)
I have a non-dedicated flash that I use in manual (and it also has built-in autometering), but I use either my 580EX or my 430EX II for the majority of my shooting these days, and only use the 285HV for multi-light setups. I got the 285HV when I was shooting with an AE-1 Program, and it was fine for that, but when I got my first DSLR I didn't think twice about getting a 580EX.
The Canon flashes are so versatile that I wouldn't be without at least one. I can do ETTL autoflash with flash exposure compensation, manual flash, remote flash without needing accessory triggers, and much more. I think buying a non-Canon flash, and particularly a manual-only flash, as one's first flash is false economy.
