Currently most forum members use a STM32F103C board, of some form.
These offer exceptional "bang for your buck", as they deliver approximately 10 x the performance of a AVR based Arduino board like the Uno, or Pro Mini, at a cost of around $0.50 more than the Pro Mini.
STM32F103C8T "Blue Pill"
This can be bought from a number of different suppliers for under $3 USD.
Note. All Blue Pill boards are manufacturered with an incorrect USB pull-up resistor, which means that the USB does not work on some PCs. So you may need to do some soldering, if it does not work for you.
Please see the wiki for more information. http://wiki.stm32duino.com/index.php?title=Blue_Pill
