One other fun thing about the FTDI based adaptors is that they are supported out of the box on the Raspberry Pi. You can setup a $10 pi zero w and share the serial port over wifi with it. Its like an extremely cheap wifi to serial adaptor! Or, they have a 3.3v serial port already on board which you can share also. Or if you get the larger pis or connect a cheap USB/Ethernet adaptor to the Zero you can make an ethernet to serial adaptor.
