Gentlemen, ive been out of the collecting game for several years. Who are some good photo dealers to buy from?

[24th Panzer Division]

I know ebay.de is obvious and I am thinking of going there as well, but I was wondering what sources for originals that you like? Specifically, im looking for original photos of Generals, and Generals like: Heinz Guderian, Manstein and Knight's Cross Recipients. Ive seen several of Rommel for sale recently-but asking price is out of hand IMO. I had had 4 originals of Guderian-but these along with a stack of my generals images-were pinched from me several years ago, and I would like to start replacing them. Guderian is a priority-because of some research ive been doing on his aide-who came from the 2nd Kompanie Panzer Regiment 1. I had two photos of the then-Leutnant-who was later promoted to Major-as seen at that rank with Guderian in two of my photos. The photos I had were two snapshots and two Army Group press photos-the AG press photos are the rarest type photos and you do not come across these. These are not the same as Heinrich Hoffmann or Propaganda Kompanie photos-and are much much rarer.

Any ideas would be of great assistance and will have abundant thanks.
