[f-nsp] Is there much to recommend an MLX?

[Clint Chapman]

Dan,

I am just going to toss out a quick vote for the XMR line. We have them
at our edge/backbone in 6 major cities here in the US and couldn't be
happier.

With that being said, they aren't cheap, but year end I am sure you can close out a good deal :)

Thanks!
Clint


P.S. Good to see another foundry guy here in the mid-west (our office is in Bloomington, IL)
