I have a micro center local so that why I got the iHome, just saw it for $1.99 while there for filament an grabbed it…in fact I got two at that price
Many people seem to like the c270…
I happen to have a hi-def stand alone web cam that I can pan and control remotely near the printer so I really only use the raspberry usb camera for the time-lapse stuff…hence something cheap. For realtime monitoring the web cam is better…It even has bi-directional sound so I can listen to the print in the background, which typically if something goes bad I can tell from the sound and then look at the camera and shut things down if needed.
