You can probably find that tank on eBay looking for moped parts.
I have been watching eBay for the last couple weeks, and there have been a few tanks that would work well, a Sachs tank auction ended a few days ago, but they usually end up going for $90+. Then you still have to clean/boil/seal etc. Mopedarmy might be a good place to look, though.
From what I heard, Imperial still has a couple boardtracker tanks left but are just hard to get hold of. I will ping them on Facebook and see if they have any left and are willing to take pity on a budget-minded builder, lol.
