Currently there is a Centuri 1/45 Little Joe II on ebay.
The box is opened, and the contents appear pristine.
Bagged items still in sealed bags.
Buy It Now price is $475.00+ shipping.
This is one of VERY few kits that I consider to be worth close to $500.

I do not have one in my collection; this is a bit steep for me to just build a kit, but I would consider this a 'builder' as the box is no longer sealed.
I probably will never acquire one as I won't pay over $300 for ANY model rocket kit.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
