I have both my MP4 next to MP5 on display with MP10 next to MP36 on another part of the shelf. Even MP2 same shelf as MP22. Still have my Hasbro MP1 in my bedroom. Have both Hasbro and Takara Soundwaves. Bought Hasbro almost solely for all the cassettes, but couldn't sell either. Also have silver Bluestreak as well as blue Bluestreak.

Delving into 3P MP too, I have Sunstreaker and 3P one. Both have their own qualities. And a 3P megs too. I'd buy an official Shockwave if I could find a cheap one. And if any other 3P I have get an official treatment, I'll buy it too

I did end up selling my Hasbro Thundercracker and kept my Takara one, but only coz I needed money at the time.

They all have a place in my displays. If there's a new Prime, if he looks good, I may get one
