Hello. Regarding your interest in the Z2, you might also try checking Craigslist ads. I have had some good luck simply e-mailing sellers and asking if they would be willing to ship an item if I make payment with PayPal (maybe 1 out of 5 say yes). The reason I mention this is because the prices can be MUCH better than on eBay or other places.
I just bought a Novatac 120T and Surefire KL3 head from a guy in California who still has a Z2 and G2Z for sale (both users). He is asking $40 each which ain't bad for the Z2 and you may be able to talk him down even further. I received the items I ordered from him yesterday so I feel I can recommend him as a seller. Good luck with your pursuit!
