I wouldn't recommend the G2 United mould (from original OP vs Megs 2-pack). I've regretted getting the 2-pack, and find the toy just unsatisfying.
Do like the head on GDO Voyager Megs - better than the cartoon/comic/G1-inaccurate head for Bludgeon/Banzaitron and the craftsmanship is much better than Gigatron's mega-face. It's cartoon accurate-ness seems really out of place on Bludgeon's Bayverse body though (I'll probably bite since I've got the other versions of this mould already).
