Replying to Canon HV30 on a Mac

I'm planning on buying an HV30 but i already realize that i'm gonna need to buy a new editing program (im still using iMovie) I have 2 gigs of Ram so that should be enough power to use the HD but what program can i actually edit with HD. I know in Final Cut Pro you can and im willing to buy that if need be cuz i'll use it forever but if final cut express can use HD footage id be more inclined to buy that. PLEASE HELP!! Thanks!
