I have purchased over a dozen fixed blades in the last year that would count as "survival / utility" knives. I've got Beckers, Swamp Rats, Scrap Yards, Chris Reeves, you name it. There are a lot of fantastic blades out there. Figure out what you're really going to be doing with it, narrow down your size and preferences in material, blade shape etc. That will bring your choices down from 100 or so to just a handful.
If I could go back to before I bought one of everything under the sun and do it all over again I would have definately started with Ranger Knives. Justin will treat you right and for $100 you can probably have something set up exactly the way you want. Look into an RD 5, RD7, or his Afghan knife. Incredible values.
The Fallkniven F1 is fantastic too and in the right price range. I own one and it is very functional and tough as nails (but a little small for my hand).
Check out Ranger Knives! Let us know what you decide on.
