If you want to get a little hacky and crafty you might try getting one of these displays. I had fun setting up mine and I love that the box gives me some direct visual feedback now.
If you search for “SSD1306” (the display driver chip) an array of options will show up. I’m using a 4-pin i2c variant, but you could get bit of a faster display refresh rate using SPI. You can enable both or either on the pi.
