Pro, The price is certainly right for the Behringer. $99. US! I have heard all the others, and in my opinion the Peavey Kosmos is best. I have a DBX Aural Enhancer that is pretty good, but not in the same league as the Kosmos. I previously had a BBE, but it was several years ago. I've gotten away from using them because "lighter is better", but I might check out the Behringer.
