You probably have heard of it, but it looks like a nice portable controller in my opinion, however they have removed the dedicated filters and alot of other features that made s4 stand out. http://www.djtechtools.com/2011/08/25/t ... more-14526 I honestly think it isn't cheap enough to make it a better/cheaper choice from the s4, as there is only a 200 - 300 difference but whats your opinion? (no I'm not changing my mind again, just looking for some discussion)
