Yep, Super rare as Tony and Nino have said, but just to upset you even more 
I have one too.
I'm sure its not as good as Nino or Tonys .
I got it for a good price not working but minus the backglass. I think this was imported from South America and only came here because it was in a lot with some other desirable pins someone was importing.
After a bit of patience I found a backglass in USA for $100.
I would say you may have to import it yourself if you really want one, or ask Mark C or Tony Pinballshed to keep an eye out when they get their next container lot.
Youre lucky to find a backglass (and get it here from the USA)
I have tried a couple of times to get backglasses from the USA but ended up giving due to freight costs.
It seems very dependant on who the seller is and where they live, I've heard a few stories about one post office saying no to posting and another saying yes, bit inconsistant.
I would like to know your secret.
Yes you are right it is inconsistent, and I know you personally had a lot of hassalls getting your backglass shipped.
I do think luck plays a big role and also it helps a lot if the seller you are dealing with is prepared to go the extra mile. A lot of sellers just cant be stuffed.
There is no secret to it as such, just ask nicely and hope you get someone who is prepared to do that bit extra.
I have lost count of the amount of times I have emailed people to ask if they will sell overseas, only to get no reply at all or just a flat refusal, but it is a bit of a numbers game , if you ask enough sellers you will eventually get someone who will help out a bit.
I do honestly think the good ole Aussie Spirit is something thats unique to us here ie: we usually help out anyone if they seem fair dinkum.
