Re: coal ?
You can pick up a small, single coil, burner for pretty cheap. i got mine for under $8.00 at Walgreen's Pharmacy. It was on sale but a comparable one at a local hardware store was about $20. So, check around. Sometime you can find them at thrift stores, too. That is, if you would prefer to use coil -vs- gas. Smoke happy.
