Currently there is an opened complete Enerjet Pterodactyl kit on ebay with a starting point of $179.95.
It is strangely listed as a "Centuri" Pterodactyl, not Enerjet.
The seller has many other vintage Centuri kits.

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, and HAVOC !
