There seems to be an ample supply of fibreglass ones available. There's a nice looking Fireflake Blue one on ebay right now (not mine, but just like my blue one). Won't rust or dent! Of course they do have some issues with cracking and dissolving...
If you want steel, well so does everyone else. $300-400 should buy you a rusted dented one with bad paint on ebay. If you're lucky it might not leak too much...
