Hi Jack,
This is a personal favorite of mine:
It was released last year around the holidays, and ought to still be available retail.
Here's another nice one that's still to be had retail:
The images of both models above are magnified, BTW.
If it sounds like I'm pushing "retail," its because I don't like buying diecast model airplanes on ****. They'd run you about $80, I believe. The best experience that I've had with buying models like this in an auction is the **** store of KH Norton (UK). There's not a great demand for "Golden Age" models over there, and they tend to sell at a good discount. I don't know if this would be an option for you, as shipping to Australia can be pretty pricey.
Finally, Al mentioned 1/32 models. They are indeed expensive, and...well...large. You're looking at a whole lot of "foot-print" in terms of display space. In terms of quality and detail, they are a mixed bag. My rule of thumb is pretty direct. The model has to offer detail that I don't see in a smaller scale. If it's just a big hunk of zinc, that's not notably better in some respect than what I can find in 48 or 72 (or smaller), forget it. Speaking of "big hunks of zinc," this just arrived yesterday, along with HM's Vraciu version:
At the risk of sounding vulgar, I suspect that something like the model above, with a stand, would cost about three-hundred Australian dollars. {eek3} Just trying to be frank.
