I don't think there's any real danger of someone plunking one of those suckers down on a contest table as is and walking away with a trophy. As nice as they may be, it'd still take many an hour to bring them up to contest-winning level.
Here's a philosophical question: at what point do we consider ourselves having "created" a model? We buy kits and aftermarket parts, assemble them, and paint them. Definitely an art, and talent is most definitely required. Absolutely no question there.
But somebody (or team of somebodies) actually created, from scratch, that kit and all those aftermarket parts for us to assemble and paint.
So, unless we totally scratchbuild, do we truly "create" our "own" models? Seems to me to be a matter of degrees only:
Acceptable: Tamiya creates kit. We assemble and paint kit to our liking. No one complains.
Unacceptable: Tamiya creates kit. Tamiya assembles and paints kit. We buy kit and do with it as we please, which may include detailing, weathering, etc. Fellow modelers look down their noses at us. "You didn't make that."
There are only 2 steps added by the model company in the "unacceptable" scenario. Granted, for the modeler, those are very important steps, but from what point can we say we truly "made" a model?
Just for the record, I'm personally not interested at all in buying built-ups. But I wouldn't begrudge anyone from buying one, or selling one.
Nor am I a scratchbuilder! Just a normal, happy kit-builder.
I do worry about the kids, though...with all the die-cast and pre-built kits out there, why should they bother building? Sure, we love it, but for a beginner...
