I would certanly not classify the 4200 as and expensive scope, nor it's low light capabilities as expenisve either.
I don't say it's a bad scope, but for example for me that uses scopes mainly in very poor light, it's not good enogh.
And as the the orignal discussion was about expensive/high end stuff that was what my answer was abouth.
So if someone can afford a scope or binocular for 1500-2500 USD then he can certainly afford one second hand of each for 500...........
And even if you really don't want to buy second hand stuff, you can always buy the favorite scope for the high end money and then buy a surplus good quality binocular and have good quality but heavy binocular.
I regards both the scope and the binocular as equally important.
If you had bought quality binoculars they would most likely not have been broken.
Quality binoculars are so much nicer to use and will be used more than cheap stuff ever will.
