$200 is not a lot for a quality knife, period. Kershaw, SOG and CS are cheaper because they're made cheaper. While certain elements of fit and finish may appear to be very well done, the finer points of quality- the internal design of the parts, even the pressure and angle at which they are joined, etc.- do not equal the results produced by higher-end makers, custom or production. People don't often understand Sebenzas because they seem too simple, and there's not enough complexity for them to see any evidence of high quality. That simplicity makes the Seb perfect (with the exception of the fiddly thumb lug), not to mention the fact that you can throw it, pry with it, put it through metal and it will still maintain that legendary smooth action and reliability. Regardless of what may be shown in their videos, CS knives will not do that.
Emersons are in a league of their own- they are unique because the fit and finish are admittedly poor, but the durability and performance are very high. I agree that they are overpriced, but by no means should you expect perfection for $200. Things cost money, and good things cost more money. In 2010, using 2010 money, you might be able to expect perfection in the $600 range if you don't ask for anything too fancy or decorative. Pay less, and you'll get less. That's why the Sebenza is such a marvel. For $300-400, you get quality and performance that is rarely, if ever, matched at any price.
For $200, Emersons give you exactly what you paid for.
