7D 580ex trigger

Line of site has been okay but I'm wanting more.  I'm would like to use HSS and not have to worry about line of site.  Any suggestions on what some of you use to trigger your flash's.  I have 3 580ex's.

I noticed Pixel Kings but I've read somewhers that you loss all the in camera function when useing the 580ex's, only the EX 2's work.

Thanks!
