Mike, Tamiya's prices darn near doubled over the last year. New releases are now just as, if not more, expensive than DML, Tasca, Hasegawa, or Trumpeter.
It used to be a newbie armor builder bought a few relatively cheap Tamiya kits at first. After feeling comfortable they then invested a few more $$ for a newer tool, more accurate (read complicated) kit. There's no difference in price anymore, yet Tamiya's kits stand the test of time as far as I'm concerned.
