I don't know about the other cheap Chinese brands, but I like the Ganzo knives. If you haven't had one of their FH series with D2 bladed knives, I suggest you go find one. I have not paid over $25 for one of them yet. The other Ganzo knives with 440C blades and Axis locks I have yet to pay more than $18 for one. I bought a bunch of these just to play around with dyeing the G10 and acid etching the blades. Gave several away as gifts, they always impress.
As for the other Chinese brands, many of them are commanding higher prices, but truly I haven't seen anything better made than these Ganzo Firebird knives. The only real difference seems, to me, to be the quality of the metal in the blades. I have a Bestec Scimitar and a Ruike Hussar that I really like, but the Ganzo Firebird FH series offer as good, or better, well tempered D2 blades that are as good or better at a much lower price.
