I apologize, I did not read this entire thread, but I assume by appendix carry, it means IWB, at about 2 o'clock. I have been carrying this way for over a year now. Formerly, I carried IWB, SOB, which really was horrible in retrospect. I will say as a disclaimer, that the amount of time I carry is somewhat limited, as I cannot carry to work, so it is only when I leave the house for non-work purposes, otherwise the carry gun rides in the car with me.
Anyways, I am tall, but certainly not slim, and my GLOCK 23 easily dissappears under any untucked shirt that is not too tight, or too short. I actually have found that my beer belly helps hide it a bit ;).
Was a little uncomfortable at first, but no more so than any other new form of carry. Now that I am used to it, no worries at all about sitting, bending over, reaching, driving, etc. The only think I don't like is when driving, the seat belt makes it hard to reach the weapon.
For a holster, I currently am using a simple Bianchi belt clip leather setup like this:
