Yeah, $70 for those pieces of crap sucks! I'd suggest a pro controller and/or an 8bitdo. They're fantastic! My daughter has a nice corded Zelda pro.
for portable controlers a good replacement option is the ipega 9163. buttons are a tad mushy, but overall its a decent controller for only $30 https://www.amazon.com/gp/product/B07WJGP9WT/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
I really like the Switch. It's shaping up to be both one of my favorite Nintendo consoles and favorite in general
