sorry I'm late on this thread.
Like guy g said, I do LOTS of research before I buy something, so I'm not let down. And, just like him, I've spent years researching sebbies, busses, etc. So when I get them, I know what to expect, and I'm not disappointed.
This type of research not only helps me pick good knives, but keeps me from buying a BRAND.
In other words, I don't buy a spyderco or busse because of the brand, but because that specific MODEL works for me.
Like Sting777 said, I'm not a fan of the entire spyderco line (frankly I think most of them look REALLY ugly). But my Chinook II is my most reliable EDC. Everything about it is tough, sharp, and dependable. But just because I like my chinook II doesn't mean I'm going to purchase a gunting (a knife that I'll never understand...it's so ugly!!).
Same thing with Cold Steel: I think most of their line is JUNK. But my black bear classic and XL voyager are SOLID performers. Heck, my trailmaster is the perennial beater. The flat of the blade has been used to hammer nails into my floor and it didn't show any scratches or damage. But sure as heck am not going to purchase a desperado or recon 1 from them.
So basically, do your research (this takes a while), don't buy into hype, and you won't be disappointed.
