Here are some interesting kits on Hobby Link Japan.

A re-issue of a kit from Ghost In The Shell.
1/72 scale means it would work as a large, unmanned drone type of vehicle in 28mm games.

The scale is not mentioned however the vehicle looks more useful as a major part for conversion and scratchbuilding rather than as a model in itself.
There are two vehicles in the kit, making it good value.
If you don't like to order from HLJ I am sure these kits will also be available from shops more local to you.
