I confess that mine came from eBay, cost about £10, but it's brilliant. I've had it for about a year, replacing one I had for about 2 years before that but lost (then found again and my wife now has in her handbag).
10 white LEDs producing a very clear beam, five ultra-violet LEDs which regularly I find useful for a quick and informal look at "what's happening there", and a red laser pointer in the middle which also comes in regularly useful for those "I mean that bit over there" moments.
Uses three AAA batteries, which I replace about twice a year of fairly regular use. So far has given me no trouble at-all, about 35mm across at the blunt end, about 27mm at the sharp end, about 130mm long.
Looking on eBay,
this seems to be the same model.
