Personally, and I know that I appear to be in the minority on this, I think that IXO are excellent value for money and display well with their Corgi and Dragon brethren
.
I will qualify myself by saying that I can only speak of the Do 335, Hs 129, Me 110 and He 219, all of which I'm proud to have in my collection. Some credit should be given to IXO for having the courage to produce die-cast models that, although not perfect, are representative of the more esoteric and unusual designs usually ignored by other manufacturers. Now if only we could convince HM, Corgi or Dragon to also do a Il2 Sturmovik!
