No...I did mean C6 (3-pin) since Jim mentioned asking

the C13 (C14 inlet).
Things may be different in the US, but C13/C14 is the most common in UK
and Europe, and C5/C6 is relatively rare, which makes them more
expensive here.
If the PSU doesn't require an earth/ground
terminal
though, the C8 would probably be a better choice since it would be less
expensive to implement than either a C14 or C6 inlet, and take up less
space.
Agreed.
The C5/C6 is now very very common with newer laptops
and IT equipment.
In the US, the C7P polarized version is extremely common with consumer
home audio equipment. Both the C1 and a coupler similar to the C1 that
is more rectangular with rounded corners (still 6.6mm c-c) vs the more
oval version in the standards are also very common with battery powered
portable radios and similar that also have an internal power supply.
I can remember only ever once seeing a C7P, and although I've seen, and
possess, some C1 cables, I haven't seen any new equipment use them in a
couple of decades. Again, possibly a difference between territories,
but I imagine the cost difference is very small. The space difference
certainly is. Another factor, at least here, is that C5 is so common,
people have cables going spare all the time, and that makes for a
self-perpetuating or even escalating commonness.
I bet we both agree that anything from IEC 60309 isn't required here,
though :-)
