I carried a ZT301 for a while. I've actually found a small fixed blade more comfortable (because its on my belt instead of hanging in a pocket).

However, I'm unwanted in this thread because I too often question expensive folders. Folding knives are the one place in the entire gun / knife / gear sphere that I simply do not spend heavily. My current folder is a PM2, and I don't even like to use it. I'm half-heartedly looking for a cheap (sub $30) folder to use for daily life stuff. All it has to be is super sharp and lightweight.
