Bestguarder 6x50 digital night vision monocular.
It is only 4 months old, works superbly and can see out to distances well over 350 yards using a nightmaster 800 but does have a built in IR. It runs off 4 AA batteries.
It has a digital zoom and takes a micro SD card so you can record what you are viewing. The link below shows some deer on my permission a couple of weeks ago at about 140 yards. The quality is better when you are actually looking through the device than viewing it on YouTube.
