I'm a bit iffy about going for something where shields are only available from one particular manufacturer - same for things like the Adafruit Feather really.
Stuff like Arduino, Arduino Nano or Raspberry Pi have loads of breakout boards from lots of different manufacturers (often at very low prices) so I think would be preferable. There must be others though?
