Thanks Katana, and others who have commented.
First , let me say that I just started collecting K&C's D-Day figures over the last 4-6 months) so I have a very modest collection. Getting off-topic, but since you asked:
My oldest figure set is DD088 GI Tank Crew released in 2008. In terms of scale and look compatability, the figures blend in nicely with newer US D-Day figures.

I absolutely love DD184-DD188 (some pictured below). They are all good quality figures and I like the $42 price tag (released in 2012; all of which are still available).

In terms of more recent figures,
DD227 Tommy Gunner from 2014 ($45) is a very nice figure; mold, face, and paint quality.

I was (a little) disappointed with the paint quality of DD273 "The Sarge" (in addition to change to a green/grass base) and more so with DD275 Capt. Dale Dye both of which are $49. (pictured below). The paint seems duller. My Dale Dye also has a strange; although slight, lean which doesn't seem like a mold design???

DD262 War Daddy was done nicely (paint quality and mold - my favorite of K&C's newer D-Day figures (not because of movie or actor)). He came out very well:

I'm honestly not sure if I'm going to buy the new Tank Crew sets (DD280-DD282). I don't like the price of $49.50/each ($99/pair) and if I buy one, I would be tempted to purchase all three. DD228 and DD229 Tank Rider Sets 1 & 2 are a nice alternative. Although not standing, they are a little less in price and have some nice poses. I own one of the two sets. I also appreciate action poses vs. figures standing around; and with K&C's movie figures, we see a lot of these.
In terms of overall scale and style compatibility among the figures I've mentioned (spanning 2008-2015/16), they all look good with one another (aside from the patches of various divisions).
My D-Day Collection (1) by

In my humble opinion, prices have unfortunately gone up without much "bang for your buck" (figure wise and not taking the Paratroopers into consideration) and paint quality has slipped a little (based on the figures that I own; although War Daddy is very nice). I believe scale has remained pretty consistent.
These figures remain my favorite of the US D-Day collection:

Good point and noted; will have to remember when I photograph.
