I'd be happy to pay a little extra up front so that I wouldn't have to deal
with the ongoing expense and headache of wall warts. Actually, I'd pay
quite a bit more, but that's me. As far as space goes, big clunky wall
warts and extra power strips are currently taking up a lot more of my space
than rack gear with internal supplies which may be an inch or two deeper
because of it.

A power supply that passes the regulatory requiremnts enforced in most
parts of the world should not have these problems. The charge from the
lightning just gets shunted to ground or blows the fuse and never reaches
the equipment. If you want more confidence, power strips with surge
protection are pretty cheap.

Wall warts will also protect you from lightning, but only because the cheap
Chinese made transformer will blow up...;-)
