One of my favorite budget EDC's (auto) is the Ganzo G719-BK. Holds an excellent edge, opens lightning-fast with a pleasing (to me) 'snap', and after years of use, the blade remains centered nicely when closed. VERY well-made knife (although a bit on the weighty-side) for the cost of admission IMO...

I also have the Ganzo G707 "Godfather" type auto (EDIT: more like the Pro-Tech "Don" series). Again, VERY pleased with the quality / dependability for the $$. I wasn't so pleased with the Ganzo 758 'Firebird' however. Quality just wasn't there like the others, and is slowwwww-opening for an auto.
