I have to agree with everyone, these are great! I bought the Pteranodon set last year and was very pleased, it's great for play or display. I'm more than sold on that Dimetrodon, considering all the awesome scenery and animals.
I also admire their brilliant archaeology-related themes, like the Egyptians and Romans. Some of those paleolithic-themed sets are terrific. I'm especially loving the Smilodon set and the Mammoth with calf. Guess I've always been a closet Playmobil fan since I was a kid. They make great quality stuff!
