Have you shopped Ebay
There was F/glass Fastback tank went of only several days ago in Australia for <$150>
I guess that would have meant going down the fast back road.. and there is the issue of buying "older' glass tanks . but there are a bargains to be had.
A mate of mine in NZ bought a beautiful Alloy tank for his BSA classic racer several weeks back ~ being the UK and him a Kiwi it cost him but he is over the moon.
I personally, bought a T120 tank, for $65 AUD, it needs a little TLC but I knew that when I bought it and although I was working on a new project bike ~ I figure I will repair, repaint and sell it on at a nice profit I anticipate ~
For one mad moment I figured being a US tank and very similar to the T160 style it would look great as a custom tank on the Commando ~ (particularly in the Aprilia burgundy/ red , I found in the local paint shop catalogue!) But in standard form we all know about that centre tube..
That would certainly improve my fuel load capacity from the 3.75 gallons on the roadster tank!
