Is the canon powershot v10 worth buying used?
The V10 is a fixed-lens pocket vlogger with a 6.6mm f/2.8 ultra-wide built in, a 1-inch sensor, and no stabilisation. I don't have a used price or a verdict on it, so I can't say whether it's a bargain. Check the Canon PowerShot V10 page for the specs, then compare asking prices against what you'd pay new.
Buying used is worth it for most cameras, since a body a generation or two old often gives you most of the camera for much less. See buying used for the general case. Because this camera has no interchangeable lens, the fixed lens and lack of stabilisation are what you're really buying, so make sure they suit how you shoot.
Budget for a new genuine battery too, as old ones lose capacity: batteries.
