for 8 bucks at Wal Mart there is a three pack of N scale gi Joe vehicles.

  these would be great for 1/144 Battletech, except the price is a bit steep for my tastes.

but it IS tempting., looks like these are sold under the Nano Hollywood branding, but seem to be the same product as the 1991 micro force,
