I can get you one for US$175....in the past very complete, with an 
ordinary 58mm M42 lens that could be stopped down, but currently they 
only come in full-aparture models....but finding a cheap 50mm M42 
lens should be easy, might cost less than US$10 in the garbage box on a 
second hand photo market (quality is hardly relevant, like 
film/video, optics are far less critical than for still photography 
on a much larger film frame).

In the past, one advantage of these scopes over digicams was their 
size about 4x8x16cm, but digicams also get smaller and smaller.
But, such a cheap scope in the outside pocket of your rucksack does 
give a whole lot more peace of mind....I did take one with me skiing 
that way, and took quite a few blows, without any padding....:-))
