Since it appears that this thread has gone this way, I'll throw these wild opinions out there:
For those individuals who just want a nice model without any work: buy a pre-built model. They can be expensive, and sometimes not as detailed, but hey, look at the work you've saved! No worries about poor fit, messy painting, or tricky decals. A nice model on the shelf, instantly!
For those individuals who demand a challenge: scratchbuild your models. Even if you pour thousands of hours into detailing a sub-standard kit, someone else still created that kit for you. Be a "real" modeller, and scratchbuild the entire thing! Don't rely on others to do the work for you! Then you'll really have a model you can be proud of.
Of course both of those extreme opinions are said somewhat tongue in cheek, but I believe there is a hint of truth in both. It is certainly true that you hear complaints about the hobby from both camps ("kits are too easy, I want a challenge" vs "kits are too difficult, I want perfect engineering"). Perfectly valid opinions, too...we all want different things out of our hobbies, which is as it should be. Our hobbies are for our own individual enjoyment.
The various opinions about price and value are of course valid, too. Of course, Tamiya now includes PE and other extras in their kits, and Dragon is increasing their prices. It all seems to be levelling out, no?
Anyway, what was the original topic? Oh yeah, disgust at the term "shake and bake kit."
Hmmm, it's never bothered me, and I've never taken it as a derogatory term...it's always meant "easy to build" to me...and I've never thought that was a bad thing!
