Drevo Gramr 84 - it's a 75% keyboard - very compact yet have all keys necessary. It's really cheap on aliexpress but worth every penny (I've got 2, both works flawlessly since ~2014). The only downside can be the fact that if you would like to customize it, you would need 3 or 4 special keys (right alt, fn, ctrl, shift) since they're in the same size as regular keyboard/letter keys.
