I posted a video about the Teleglass T3-F. I think the glasses-like look of the display is a good feature but i don't know if it is cpmpartible to the AR-technology.
The only consumer model currently on the market is the Vuzix iWear line with an added exterior camera attachment (my article includes a video demo), but it is not stereoscopic. Vuzix has a stereoscopic AR model coming out in the fall (also requires a stereoscopic attachment, also made by them). Lumus Optics has a model that they've prototyped, but I understand they are still looking for venture funding before they can take it to market.
My article also has links to several consumer grade HMD models that can be used for VR but not AR.

WorldViz has some very high-end professional AR models if you have many thousands to spend. Theirs is a modified version of a NVIS VR HMD. The NVIS models start at about $25,000.00 and go up from there. The WorldViz AR rig is then an add-on modification above-and-beyond the cost of the NVIS unit.
