You're probably not looking at the cheapest Benchmade dealers. There are two that I know of that sell Benchmade cheaper than the others. The forums sponsor one is GP Knives.
You should do a little research before asking a question like this, though. We just had a thread with this exact question a few weeks ago. It devolved into a massive argument because most people here dislike Cold Steel, but they have a few diehard fans. A big part of the problem is that many new members come here knowing nothing about knives, but thinking that Cold Steel makes the "strongest, sharpest knives," then they argue back whenever anyone tells them differently. If you honestly do want to know if Cold Steel's knives are good, though, consider this: Cold Steel's knives are made in Taiwan with subpar fit and finish and bottom of the barrel steel. They only back their products for one year, and even within that one year warranty service is pretty shoddy. A knife with similar materials and build as Cold Steel's most popular models would be something like the Enlan EL-01, and that knife costs under $20 shipped. But Cold Steel sells their knives for as much as better-made American or Japanese knives with better steel and lifetime, no questions asked warranties. The strength of the lock is the only advantage Cold Steel's models have, but considering that no one's having problems with normal locks, this isn't really an advantage. Besides, there's much more to consider in a folder's strength than just the lock.
So yeah, you can get a lot more for your money if you avoid Cold Steel.
