ok so I have read 20 pages of the other post on this - is it easily available?

most of the online music stores in australia list the cheaper (vicious 1 & 2) but not the DT Sig. model.

It isn't available yet.

When it is available, I think it's going to end up having to be a special order for most stores. No offense to Dev, but I don't think many stores are going to be keeping it in stock, as it's won't be all that interesting to non Dev fans. It's the same with Cory Smoot's signature Schecter, and a few other artists. If you talk to your store they should be able to call their Peavey rep and find out an ETA for you. Be warned though, sometimes it takes way longer than they estimate. I've been waiting nearly six months for my 8-string Schecter

Which 8 string Schecter? I just got a Damien Elite 8 and it is killer. Very impressed with the quality for the price.
