I donno what exactly you consider "cheap" but there's this one on Amazon, I got because it looked cute honestly, but it's only like 30 dollars versus the Nintendo which is like 70(?) https://www.amazon.com/dp/B08QHJ1Q38/ref=cm_sw_r_cp_api_glt_i_QZH2X20P7SFFDFV4KM8D?_encoding=UTF8&psc=1

Also if you just search "Nintendo pro controller" on Amazon the first few results are like 25-30 dollars
