He said in an interview that they were designed around the MA306, BUT they were tested and did fit all common 306's, i.e. Cisco, Joye, etc...
As far as the aluminum body is concerned, the grade of aluminum was chosen very carefully. Also, Aluminum toxicity is only a concern when the aluminum is heated greater than 500 degrees. Anyone who owns the original Torpedo Tank can testify that it is just fine.
Also, as far as the email confirmations, I got ahold of him tonight about it and he said that all the orders were recieved, and he is looking into why we didn't get email confirmations.
I can only echo the thoughts about the DCA not been sold with the three top sections. I'm very disappointed
I've ordered one anyway in hope that the other 306's I all ready have will fit. If they don't I'll cry.
