As much as I like my clones, most people don't know much about them. IMHO, I would bet if the owner of the C-100 tried to trade it in for a different gun at a dealer, they would only allow $200 for it on the trade. I would wait another week or two and see if the prices drops.
I have no experience with a CGW parts, so I don't know if that would change the position of the DA trigger. I usually have my clones cocked and locked. That puts the SA trigger quite a bit farther back than the DA position. This works great for me. If the DA trigger position really bothers you, I would check out all of my options before I purchased the C-100.
