Banggood.com has these cheap, high efficiency DC:DC step-down modules.
Including shipping, these are 20pcs for $13.98 (USD). They step 4.75 to 23V input down to 1.0 to 17V output. Rated for 1.8A output, 3.0A spikes (YMMV). 30mV ripple, no load, so they say. I have yet to test the modules for electrical performance, but reviews are very positive. I also bought a batch of humidity/temperature sensors at the same time and they are about the same size. I was able to store these sensor boards and the 4-pin header strips with them in the same bin size as the DC:DC modules. In the picture there are 20 DC:DC modules and 10 sensor modules with header pins shown, with room for 10 more of either.
