Toysrus had these on sale yesterday for 52.99, and with Afergs recommendation I picked up the set. very nice.
I described it to my girls as 1:18 scale tank, at least what served as a tank hundreds of years ago.
Picked one up at my local TRU today. I opted for the basic elephant and rider (tempted to call him the driver!) and it was on sale for 29.99. It is quite nice, and may give my Romans a run for their money.
