I bought the Dr Wu Beastbox/Squalktalk and have the Slamdance set on preorder. They're bigger than the legends tape bots, but not by too much. Basically, they're made for + good with mainline figures, too small for MP, too large for Legends. How much you can forgive their scaling issues for Legends or MP depends on the person. Personally, I have three sets of Tape scales. My Season 3+4 shelf has an MP Soundblaster with all of the MP Tapes - including the KFC MP Squalkbox set and KFC dino cassettes (Overkill, etc..). My Season 1+2 Shelf has a MP Soundwave with the giant MMC Tapes of Rumble/Frenzy, Laserbeak/Buzzsaw, and Ravage. My Legends shelves have Magic Square minibots with the Toon MS soundwave on the Season 1+2 legends shelf. With the Dr Wu Squalkbox set as part of the group. I have the metallic Legends Soundwave in my TFTM display. I had MS Legends Soundblaster on a titan shelf with Iron Factory Galvatron - at the feet of Trypticon and Scorponok.
