Wow....I really need to start cranking some vigolixes out myself. If someone is willing to pay $300 for that, then I might want to make a run of them.
And for the record, I am quite chuffed every time I see any incarnation of a Vigolix, even ones that are a little disproportionate or unorthodox. Maybe I am helping bring a few people into the hobby, and maybe I am helping some parent pass on something to their kids. A lot of it reminds me of early BYOAC work.
