Welcome Kyutsa,
I'm new here as well, but wanted to give you a heads up on the Takara Tomy Seekers.
I have been collecting all of them since MP-03 back in 2003.
The original MP-11 Starscream/Thundercracker/Skywarp mold is better than the newer remolded MP-11 Conehead seekers.
For some reason the waist is very lose on Thrust due to the design of the center punch rivet inside the waist. Ramjet is a little better, and I have not received Dirge yet.
As a set they look great together, just don't be alarmed when you start buying the Conehead Seeker molds to find the waists to be loser than you would expect.
In my eyes they are not worth the high Takara Tomy mall exclusive price point, but I paid it just to have a complete set.
