Reply to what is so great about the vestex vci 100?

Ok i have been doing alot of research looking for a midi controller that is easy to transport (i have a numark ns7fx) i have been using the mixtrack as a knock around controller but i have come across a great deal for a Vci se arcade controller and want to know what is so great about this controller. to me the layout is seems strange and people are saying that this is a professional controller. what exactly is so great about the vci 100??
