Same thing, except when they changed their name to Merlin the quality got progresively worse. They also used the name Valhala toward the end of their reign of terror.
Roden started as Toko. Their quality improved as they gained experience. The reason that I like them best is a combination of subject matter, quality and price. They are a good example of a company that doesn't have to rape your wallet to give you a nice kit.
