Neal Catling's alloy tank is a tidy enough job
Harris Performance use to have Monster Alloy tanks along with others in their catalouge, pretty sure it was Asa Moyce making them for Harris.

The Guy that did my 2 into 1 conversion said he could do me a Alloy tank, but with most these things they are never going to be that cheap if they are hand built one offs
