Reply to Kdj-500??

I am on the verge of buying a controller and have narrowed my search to 3 controllers :-

1. Arcade Edition VCI-100
2. KDJ-500 (with a NanoPad to control effects)
3. Reloop Digital Jockey 2 (Conttroller Edition)


I've been searching the net to find info on the KDJ-500 and cant find much on this unit. So if any of you guys have got any info, cons, pros on this product, that would be great and very much appreciated.

Thanks in advance
