Perhaps the most interesting information would be:
- in general, how much does it cost to make the sort of shields we
have in GTA02 (maybe just show him the FreeRunner) in prototype
quantities.
- in general, is this kind of shields a good choice or are there
better ones ? It's intentional that most of the shields are
removeable, and such shields are more expensive than non-removeable
ones.
- if he'd have to DIY, how would he do it ? Assume the availability of
a 3D CNC mill and shops that sell thin metals sheets, particularly
brass.

The GSM module already comes with a shield, so I don't think we need
anything else there.

Yup, that would be most likely candidate for a new shield. I wouldn't
put too much effort into this, though - the AR6001 is obsolete anyway,
so all this would really amount to is an exercise in shield-making.
Thus, I'm not sure we'll actually make any new shields for gta02-core.
But it will be good to know what our options are if we have to make
shields.
Thanks,
