CRKT is very good for the money. Generally custom-styled knives (or at least, featuring the name of a custom maker) for a real reasonable price. My CRKT Mirage is definitely the best $14 in knife money I've spent. Again, don't go by the list prices on CRKT's site, you can get them for MUCH cheaper!
I would add Cold Steel to this category. Good bang for the buck. CS actually uses better steel than CRKT, but the overall knife comes out looking a little cheaper. Functions flawlessly, good steel, great lock, but looks cheap (those cheesy scales).
Now there are a number of others out there, whose names I haven't bothered to remember, that are pure unadulterated JUNK, and they still want CRKT-like money for them. In this price range (sub $40) you really do have to physically hold them in your hand to rate the product. The "S&W Cuttin' Horse" I looked at recently, which was marked $35, wasn't half the knife my $14 CRKT is, for instance. (And the S&Ws are *good* compared to other knives this shop had!)
