Go into China-Town (most big cities have one) and look around in different shops, when you see one with a good selection of Everything (yes ingredients too) ask the guy or gal at the till/checkout to recommend a wok, you must ask what they use! and be humble that you respect their advice and don`t want Sales Talk!
this is exactly what I did many many years ago, and I was actualy taken into the back room up the stairs and into their Kitchen to see what they used (also managed to sweet talk some cool ingredients off them too), and so I bought what they had
and bought a bottle of rice wine also and gave it to the lady that showed me these things
how can you get better than to ask someone that uses a Wok all the time, I have about 7 Woks, each are for different things, it`s important also to state what you will cook with them on Elec or gas etc...
Wok ownership is an art, one that when you get used to, you`ll never look back
