Endoscopes, borescopes, where to find a good supplier?
Me and my friend have been looking into getting some more optics to the arsenal, but it seems to be half-impossible to find anything else than those crappy USB-snake cameras and when you do find something other it seems to be Storz and costs easily north of 2k.
So, where do you guys buy these without breaking your budget, we are generally looking for 4 mm diameter in lengths 175 to 300 mm and with different view angles, but of course more is better.
