I recently purchased a T67 as a back up to my NM. Honestly, it was utter rubbish. There was so much play/wobble in the head that it was completely unusable for field work and the beam was average at best. It was hastily returned the next day.
I have to agree with Lamp_Shy. Night Master all the way. Yes they are expensive (damn expensive!!), but when it comes to NV illuminators, you get what you pay for. I have an X Searcher head on mine, with an AS pill fitted and I would put it up against anything else on the market for performance.
