I'd go with FOV, much easier to find, 21st Century is out of business and some of their vehicles are pricy in the aftermarket.
Go to a toy soldier show and see dealers all bashing each other over the heads with folding chairs trying to sell FOV to the customers 5.00 less than the next guy, it's loads of fun..................I remember at the Secaucus New Jersey show couple of years ago the guy next to me had a wall of FOV vehicles 8 feet high on his table (here's a hint for you novice dealers out there; break down and buy a second table, it's a lot easier to work from behind two tables than one unless the extra 40.00 blows your whole profit margin) and was selling them for half price, 40.00ea instead of 80.00ea, collectors were shoving each other out of the way to get at his stock.
He sold all of them and when the dust settled, I asked him why he was selling them so cheap, he said his wife was on his case to get rid of them all, he took a 30.00 hit on each one as he paid 70.00 each for them.
I guess he was making it up in volume.............:rolleyes2:
