I use a Trangia alcohol stove for this, mostly for boiling water for dehydrated backpacking food and for coffee/tea. I take it camping but also on not-too-hard day hikes and on picnics or beach days. I got this kit initially but I've substituted in a GSI kettle and added a windscreen (which is essential). There are lighter alcohol stoves out there (buy or make your own) which is what I would get if I had to replace this. I like the whole alcohol stove thing since it's simple and durable and the fuel is cheap and common.
Not sure what your cooking plan is, but my husband and I like to cook with these small backpacking stoves: http://www.amazon.com/Trangia-327508-28-T-Mini/dp/B000LN7HUC/ref=sr_1_2?ie=UTF8&qid=1461855978&sr=8-2&keywords=trangia . What's really handy about them is you just need alcohol for fuel, and that's easy to find almost anywhere you go. We have a fuel bottle that we fill, but we've found that when we fly this gets tricky even though the bottle is empty. Make sure if you travel with a stove like this that all parts are fully empty and disassembled when you fly. They kept parts of our fuel tank for the stove once when we didn't do this! Since then, we always take it apart, clean it, and dry it - then leave it apart in the bag for the flight. Since doing this, TSA has never kept parts of it.
Not sure if this is exactly what you're looking for, but I recently got a small alcohol stove called "Mini Trangia" for hiking that was only $37 (it even came with its own pot and lid but it's just fine to use others). Have tested it out and it seems non-fussy and reliable. One thing to keep in mind is that it only burns for about half an hour and then you have to let it cool before adding more fuel.
This is a great alternative to the DIY pepsi can stove and you can get it even cheaper without the extra parts. There's quite a few alternatives out there even within the Trangia brand. And the alcohol can be found pretty easily and relatively cheaply at hardware stores in the paint thinner aisle.
