If Takara were to make some valks with the same detail and care of their Alternity line, I'd be hard pressed not to pick them up...I am very impressed by my Alternity Megatron engineering wise. A very detailed interior of the car, rubber tires, reflective mirrors, engine detail (however minor lol), and nice use of diecast. All in a 1/32 scale compared to Binaltech/Alternators 1/24 scale, which makes for a killer toy, and the best TF line out there imo.
I'll probably stick the the regular release of the Monster from Bandai simply because it comes with a Ranka Monster girl stick if i choose to put it on (unlikely though)
