I'm sorry if this is not the correct place for this. I use to have a $100 hand held usb microscope. We had this setup in a X Y dial indicator fixture that allowed us to measure objects via the crosshairs in the software. Need to replace the scope but have not been able to locate one that includes software with crosshairs. Does anyone have a lead on something like this? ToupTek out of China has one but I don't see any dealers in the USA,
