Ahh I didn't notice you were in OZ, my mistake. I went and did a conversion on XE.com and according to it yeah even though the number is higher, its about the same actual value (Said that $90 AU is around $63 US)
And yeah ours has gone up too, last time I saw an Enzo like that was around a year ago in a LHS that was in another town, and it was around $50 then, so that'd be about the same jump (xe said $25 AU is $17 US)
Generally, I don't notice Tamiya TOO much in local stores just because they're so much more expensive and generally are a tiny selection in the auto side, while their aircraft/armor section is mostly Tamiya. Usually worth every penny. For instance I've built two Ferrari 360's.. the tamiya and the revell .. yeah Tamiya was twice as much but it was just so much better.
Right now I have three LHS.. a Micheals (national chain), a Hobby Lobby (also national chain) and erm.. I forget the name but one that's just a guy and his son running it. They're the easiest to work with but their selection is so tiny. For cars all their stuff is like mid-range releases, usually in the 90's, and almost all monogram/revell/amt.. the only thing they have over the other two is a good selection of fair priced Revell of Germany cars. Micaheals doesn't carry ANYTHING Tamiya.. and Hobby Lobby.. last time I went in there a couple weeks ago they had.. 3 tamiya cars. haha
And I totally made the convo go sideways XD
