I picked up my Z1 CSCEK in 2013. I didn't find any other external options at the time but my search may not have been exhaustive. Someone told me that the Z1 kit was just copied from the external slave solution that Nissan put in the 350Z after it had problems with internal CSCs failing. I never bothered to verify that but it certainly makes sense.
