They can be either original G1 Micromasters or the Siege/Earthrise versions, as long as they are consistent in resembling the original toys (the two members of the Air Strike Patrol released were not, as they had Cybertronian jet forms).

I did look around, but 75USD for a 4 set or 100-115 USD for a Micromaster Base is a bit too expensive for me.

Also, if anyone knows of where I can find the Countdown Micromaster that came with Titan Omega Supreme for sale separately, I'd like to know where I can purchase this.
