i'm trying to figure out which program is the best for creating electronic music, i have garage band and harmony and i'm in the process of getting propellerhead reason 3

Cool! I don't know any programs, as I don't create music, but it'd be awesome if you made your music sound like Bitter:Sweet's music. :]

I LOVE Bitter:Sweet.

Reason 3 isn't too bad, all in all, but it's far from perfect. I'd suggest getting some hardware too. 'Electronic music' is a very broad term, and I could possibly offer more advice if I knew what kind of music you were intending to make. For example, it's a long shot between industrial and hardcore.

ya, thats true...i guess i'm trying to go for hard trance and tribal types of sounds, my friend is getting a new synth right now and we're going to start making music together, we wanna create stuff like what infected mushroom makes and GMS

Get a keyboard, a quarter inch adapter, and a patch chord. Hood the keyboard into your computer. Record with a program like acoustica.

For psytrance and goa, Reason is actually pretty good, though it's far from perfect. You're going to want some kind of DAW that can handle raw patches from the synth/s as well as software. I'd personally stay away from Cubase, as it seems to have severe latency issues and drops a lot of MIDI notes randomly.
For psytrance, although it looks almost toy-like, I'd suggest Ableton Live. It's easy to use, and as far as I can remember, you can use ReWire to run Reason through it. Don't quote me on that though.
