I briefly owned the origina Mini Air Ranger (that's what I called it; I'm not sure of the official name). It had blue aluminum scales and a bead-blased spearpoint blade approximately 2" or 2.5" in length and a metal pocket clip.
I never really used it and ended up selling it on eBay (I decided it was too small for my own EDC purposes), but it was a nice knife. The model I owned was released about 4 years ago, during the last day of the Gerber AR boom. Like my AR, the Ranger was solidly made and had good fit and finish.
I can't speak to the full-size Air Ranger, but I would advise you to check on the origins of the particular knife you want to buy. I've heard (but have no personal proof, so don't quote me) that the contemporary Gerber knives out of Taiwan have had consistent quality control problems.
There's not a Gerber on the market I would pay MSRP for, anyhow, but many come up for sale on eBay and my local retailers carry them for a decent discount off MSRP.
