Nice review. I bought a set of these at Salute. I already have all my colonials covered with BTD and Redoubt in metal, (and I like larger figures anyway) so these were superfluous to my needs but I bought them for spare parts. The heads are quite large and useful for upgrading some tired older ranges of figures, for example the BTD, who have rather funny helmets, or the Queen and Country figures, which have underscale heads. I have already used some of the arms and a set of legs on some WW2 figures.
I agree that these are far better than the Warlord and Wargames factory plastic offerings.
