Cheers guys! To be perfectly honest, I've never seen any reviews of their stuff, positive or negative, so my opinions are based purely on what I see in front of me and they're flippin' great!
They're also FOUR QUID per model!
My next big purchase on the Cold War front was going to be for a stack of Saxon APCs. Skytrex make the best ones, but they're £8 a pop... For £3.50 a pop, I think Butler's will get my money.
