In my experience in following Centuri kits, $306.00 is EXTREMELY high for a Centuri Saturn V in ANY condition short of being hand-signed by Lee Piester. This price is closer to what I would expect one to pay for a 1/45 Little Joe II.
But then again, one could refer to the old saying about a Fool & his money are soon parted.
This kit is not even what I would consider rare. Although I never liked them, the Super Kits are much more rare than this kit and those do not sell for anywhere near $306.
