This is what a $15 stove looks like

Here's a good example of a $15 stove. Old, dirty, but not rusted. Parts inexpensive and easily available.

It's a 413G which makes it a 1960s stove. The original manual for this kind of stove is online at Coleman (pdf) and has delightful graphics.

This kind of stove makes for great camping (NOT hiking, it's a called a "suitcase stove" for a reason). Also nifty for cooking stinky foods outside or canning. Or, for you all-electric folks, cooking anything at all if your power goes out. A camping stove means you can cook no matter whatever else happens.
