Reply to Vci 300 Upgrade

Hello everyone, i recently got myself a vestax vci 300 arround 1-2 months ago and im pretty amazed with how well this mixers were made, altough they lack of fx so bad.
So what i basiclly want to do is to upgrade my studio to start working with my baby .
What side effect tools would you suggest me to buy that are easy to be mapped by my vestax 300 and full in effects?
I was believeing on buying a Korg 3 and a small trigger finger..
What would you suggest? or should i wait for the new vestax fx controller?
