FWIW I have used the Radio Shack mat and wrist strap to build my K2/100 and
KAT100 along with my K3/100 with no problems.

So many good idears regarding the mat. I've decided to go with

I doubt there'd be much likelihood of problem as I've never fried
anything in computer assembly since I first assembled a Heathkit H8
(which I used as a bulletin board back in 78) but

Thanks for the suggestion of Radio Shack. I really hadn't thought of
them. They and Lafayette Electronics used to be such a great source
of so many components, walls of stuff but much less so today.
As reviewing the assembly PDF in advance shows, I will be best
advised to have one during

They really are static dissipating mats. They intentionally have a very
