Cheap cookware from Chinatown restaurant supply store

I was in a restaurant supply store in NYC Chinatown today, and was tempted to get some of the stock pot for like 30 dollars, but was a little skeptical.

Are their stuff any good? I mean they are for restaurant use so it must be of professional quality, right?

If even the pro uses these cheap cookware and cutlery, why can't a regular home cook use them as well?
