What about meth/alcohol?
Sure, I love my Coleman single burner, and my MSR Whisperlite, and even my Coleman 2 burner propane for car camping.
They've all been stellar, lightweight, compact etc.
But I got bitten by a radioactive pop can last year, and started on an ocd journey of diy.
This site imho is the goto for DIY backpacking stove info:

Zelph is wealth of information as well:

I also made some Hobo stoves, and discovered the homemade version of the BushBuddy (here's one example from another GREAT website):

This beauty is my most recent DIY and maybe my favourite:

So far, I've made >100 alcohol/methyl hydrate stoves from (mainly) pop and beer cans, a dozen wood gas stoves, 2 Nimblewills and multiple cooksets (bottles, pots, etc).
The woodstoves can be combined with alcohol (pop can, trangia, etc) stoves and solid fuel tabs so I have a 3 fuel stove system, low impact/weight/cost.
I have little stove sets of various styles stashed everywhere (and piles of empty cans just waiting) - I could boil up practically anywhere, anytime, but I sometimes give them away to people I meet who express an interest...
Caveat - you may end up liking this hobby too much...
Just to say, you don't have to buy to get a compact reliable stove.
