10G tester recommendations?

[Bryan Holloway]

We're in the market for a hand-held 10G ethernet tester, and I was 
curious if the NANOG community had any recommendations or experiences 
they would be willing to share, negative or positive.

Currently we're looking at the EXFO MAX-800 and NetScout's AT 10G, but 
we're open to other suggestions.

Thank you!
