Hi, all. This post is not spam. I'm just a long-time lurker.
I became obsessed with the Z-600 for a time before the fever subsided. It has been discontinued, but still available from certain retailers in Canada. If you simply must have it you can probably find a way to ship from Cosmo Music
It's nearest cousin, the Z-555 ( not the same, I know) is also on the outs, but there are still a few available at Amazon for about half the original cost of the -600. Let us know how it turns out!
