Which used multimeter? Wavetek, Fluke, or Ideal?

Noticed that old Fluke meters are selling for $50-$80 whereas
comparable Wavetek meters, same features, sell for $10-$30. Any
suggestions on whether the extra cost of a used Fluke is worth it, over
Wavetek? Also, is the Ideal multimeter really a Wavektek? (Buttons are
in the same position, same functions.) But, why cheaper?

We were using DMMs in an environment
where we we creating 15kV pulses with fast edges.
The uPs in all the other DMMs freaked out.
Only the OLD Fluke kept reading consistantly.
