Well, It all depends on what you are going to use them for. I have two of them and I don't use any of them right now. There was a time when that was all that I used. But I do use them occasionally (only one at a time). You won't need the whole stack for smaller venues, but they haul balls if you can get em' outside(and if the soundman doesn't pee his pants when he see's you and the Bass player stacking them up onstage). I think they are well worth the money. They kick ass for recording too. Again it all depends on what you are going to use them for. (they look cool too!)
