Korg er 1 good idea?

Got the original kaossilator and thinking of running it through an er 1 for more functionality. Are there other alternatives, is the er 1 worth it just for itself (looks awesome) and how much should I pay for it (one on ebay at the mo for £100)

Any advice would be helpful

Is there a sync option avalible for traktor as well.
