Just looked around a bit more extensively. Prices and manufacturers vary surprisingly this season! I like a Spectra CR20B for $268 just fine for now. Admittedly, it seems true that B-body tanks, 19-20 gallons run about half the cost, but its clear that this is a buyers market for the present. I sure as **** don't mind popping between $220-300 for one made for a C-body of decent steel. As you know WELL, Sunny Southwestern roads run looooonnnnnngggggg, so full capacity gas tanks in our corner are the prudent shopper's safe bet.
