I'm using a
PicoReflow.https://apollo.open-resource.org/mission:resources:picoreflow 
It's Raspberry Pi based, so the board cost is about the same as an
Arduino, but I use my tablet as the user interface AND tweaking profile
is trivial unlike most of the Arduino based stuff. The system uses an
internal web server and can be connected to a local monitor, or a web
interface. All the control logic is in Python. I used the tablet browser
and I don't need to stand next to it to monitor operation. This is
particularly handy when I'm baking out parts.  I hand wired the
interface board (trivial I/O) and used a purchase MAX31855 based board
for another $20 from
