I am about to run a whole ton of communication cable in an existing two-story house, and so I am considering buying an inspection camera to help with this. As I started looking around, they range in price from about $75 on sale to $800. I'm not a pro contractor, but this will be a tool I use a few times a year (mostly to help fishing wires), so I don't think I need anything really high-end: One model I was considering was the Royobi Tek4 Inspection Camera (which is ~$140).
What all the sub-$250 units seem to be missing is the ability to store images ("take pictures") on an SD card or whatever.
So my question is this: if you own an inspection camera, how often do you actually store images, and how useful is the ability? If you don't have a model that can do this, do you often wish you did (or end up using another camera to take a picture of the screen)? For casual, non-pro use, is it worthwhile to spend $100+ additional on this ability?
