Almost any ani-static mat and wrist strap will be OK
My testing has shown that not all anti-static mats are created equal.

I've just measured my a/s mat. I used two small metal boxes about 4 x
2, spaced 3. I applied 13V thru my DMM and pressed fairly hard (thru'
good insulation!) to get 0.2uA, giving a value of 65Mohm. RH here is
probably 60% or more. Pressing lightly gives 0.1uA, the smallest the
DMM indicates.
