I think we need to fully distinguish the camp guards from the Waffen SS the armed part of the service. It does seem that some confuse this and lump everyone in the same boat and, its always the LAH figures that get the rise from those who wish to cast aspurtions against the whole of the SS.
The Totenkopf and Teddy Eiche (3rd SS division) were derived from camp guards the LAH and Das reich were not. That does not mean there were not members who were involved in the design (in terms of the workings) of the concentration camps there were but, on the whole these divisions were front line.
The Gestapo and SD et al were the main protagonists of these actions. Yes, they were all under the banner of a regime which, was totalitarian and, had dispicable goals but, they were doing their duty for their country whether or not that is palatable for some is neither here nor there.
I think should you wish to collect the LAH which I do then you should collect regardless of what others say or think. We collect from many era's where dispicable things were perpetrated against combatants and non combatants spreading across hundereds of years.
Personally I like the display that they achieve though, I do not collect any of the other ranges under the banner of Berlin 38 only the LAH everyone is allowed the right to buy and display what they want. I make no distinction to the parade figures and the combat troops that is my view of these figures. When some say you are a supporter of the regime if you collect parade figures IMO you support it no more or less than by having several armed units which are of SS.
One also has to remember where does one draw the line. Many actions including the Einsatzgruppen and the concentration camps could never have been actioned without the support of the Heer. So, what do we do buy nothing german???
Buy what you wish the Berlin range is probably one of the most popular ranges available and, why many of those who hate these figures are able to collect the ranges they do. If you want them buy them
