An update on this subject...
In a nutshell:
I needed a tank and could not find one at a reasonable cost. I have the resources to build one but really prefer not to.
I posted this thread, if I add up the guy's that said they would buy one if I were to make them there were three or four commitments. Not bad but not great for my time & expense.
My best buddy sixnotfour
alerts me that a brand new tank has just been posted for $400.00 in our classifieds by THOMAS. I just got confirmation & it's a done deal.
Unless Dave ( DW Design ) decides to stop making these ( he is thinking about this) I believe I'm onto the next obstacle.
I'm sorry for the guy's that are still looking ( LarryR) but I think DW Design is your best hope at this point.
Thanks to all who got involved on this subject.
