The tablet I use is a Huion for reference. It's travel sized and works very well for me so if you're looking to get one definitely look and see what you want. Mine has some short cut buttons on it so I can program it to use like Ctrl + Z or Ctrl + N and such. Other tablets lack that but have the screen on the actual tablet whereas mine does not. Those tend to be bigger too so they're harder to move around whereas I've used mine on planes and such.
