Obviously, it depends on how good a price it is
I agree with mental about the light grasp, but the mount itself is worth a few hundred $. It's a philosophical difference, goto or push yourself
I "upgraded" my setup with a C8 and there's a noticeable difference between the C6 and the C8.
The 130p will give you the wider FOV for sure, the C6 will just give you a little bit more depth with its larger mirror. I still use mine occasionally as it's so small and light/portable.
