For a budget controller, the Retroflag had a shockingly good d-pad. I used that for years with great results.

This is the one I usually buy. I like to make retropies as gifts for friends and colleagues and stuff.

Keep in mind, there are no plug n play controllers. You have to map each new controller. I'm sure any how to you watch will recommend this, but start with a keyboard, then map controllers.

Also, it's not difficult at all to build if you're a beginner. The process has been so streamlined, that anybody can do it. Don't be nervous, it's pretty hard to mess up.

Feel free to dm if you get stuck or have questions. I love building these, and sharing that joy.
