Another model on their site http://www.tokyo-hobbies.com/74jgsdf.html is a Japanese Type 74 MBT. This one is 1/10 scale.

Although they look like ****e, one thing that is appealing is that they seem to be quite rugged (could possibly need some bracing in the tub) so they should be great for doing it tough out in the field. I worked out that it would cost a tad over AUD$2000.00 including delivery to Australia, which seems promising. A little bit of cosmetic upgrades could make it quite presentable.
