I just got this one
14 Inches Carbon Steel Wok with... https://www.amazon.com/dp/B00390HPHE?ref=ppx_pop_mob_ap_share
It is a wok, it works! I don’t do rivets. It seems very similar/identical to the wok shop ones.
I'm very happy with [this one].(https://www.amazon.com/dp/B00390HPHE/ref=cm_sw_r_apan_i_FDRJVT2FC7XE6Q76VWMM?_encoding=UTF8&psc=1) 14 inch 14 gauge carbon steel with flat bottom and wooden handles.
This one from Amazon is very good, but a bit pricey.
This one fits the criteria of being carbon steel, flat bottomed, 14 gauge, and 14 inches in diameter with a helper handle.
