I am waiting on a bsa b50 slim line alloy Tank from the States, It cost me big bucks and I have sold my other Hi -point Alloy tank for big bucks , and they are worth the money, try and make one see how good it will turn out, I bought a brand neworiginal Dot Tank from UK $750 delivered.
over the years I have paid $300 to $350 YZ 125 and 250 A tanks, getting hard to get, grab them while you can.
