Opinions and possible first hand knowledge

I am looking for a CF bottle to fuel my new airgun obsession and was wondering if anyone had and thoughts, opinions, or actual first hand reviews of the following:

They appear to have a few different offerings and I have been sorting through them all.

Also if anyone has a recommendation for a regulator that I can hook up to that which would keep me from accidentally overfilling my rifle I would appreciate it. The Benjamin Armada is what I am picking up now. With a possible FX Dreamline in the future if things work out with what I am planning.
