Loop Libraries

I have some loops, but need to build a library. Mostly rock/blues, and mostly flute sax strings. I have plenty of kbd and drum loops, and we play the guitars and bass.
 
So, any tips on cheapest(but useable) loop libraries would be welcome.
 
The idea is to add some flavor to the rock/ballad type tunes.
 
PS - I do have an acct at Loop Loft if that matters.
 
As always, thanks heaps!
