"Atari" USB Joystick recommendations?

I'm just scratching the surface of emulation. I bought myself a Raspberry Pi 3B. It has retropie. I downloaded some Atari ROMS. It came with a SNES-type USB controller. But it's just not the same without the single button stick. I did a quick search and the first two I found got crummy reviews. Anyone have any recommendations?

Thanks in advance!

The Atari sticks might not be enough. You'll need a controller that can simulate the switches on the Atari 2600 console as well as movement controls.
