A good quality fixed blade will last a lifetime (or more likely, until you lose it), so I don't think $100-200 is an outrageous investment, even for someone that doesn't feel the allure of high end cutlery, but obviously I'm biased.
Mora's are great abusers, but I've broken a bunch of em, enough to have justified at least one higher end knife. Not trying to disparage them as awesome tools however, if you're *interested* in knife work, they're awesome to beat up, and great to hone your skills on, so to speak, and remain one of the best values period, along with the Opinels.
If you want a reasonably inexpensive no-nonsense performer that'll last as long as you can keep up with it, the BR's are one of the top choices IMHO. Esee (used to be RAT) is another great and often cheaper option, the Izula can't be beat for the money, although their bigger stuff tends to be chunky and weighty for my tastes, and I don't find it performs as well. They have a much better warranty however, pretty much no questions asked replacement if it breaks, so that's one thing to consider.
Anyway, lots of great options, but it really depends on your intended use, and desires.
