right, I'll give my opinion, your choice to take it or not.
I recken you cant go wrong with either an Ashton Justice, onza limey or echo control (although the first two are british companies (Y) )
as for front brake, I say get an avid if you are on the cheap, hope if you want great customer service or magura for just goodness (all disks by the way)
as for the rear, cant go to wrong with a maggie, but dont cancle out a vee if you can, they are REALLY underrated.
my view on things
Edit: Forgot that koxx also make nice riding frames, levelboss and beleay are my faves
