I have the QuickDraw trigger and the extension tube. I've been waiting to get the glass Sherlock as well, but I don't know when I'll find one of those. The extension tube is worth it though, and always keep in mind that it's easy to fabricate some things of your own!
Congrats on the purchase! I like the gold color, mines blue. All in all i can definitely say it is the best dry piece i own.
