We have been using Ciena switches for QinQ.

CN3920 would fit best for low cost. Pretty easy to use. 

The 3916 is one generation newer, cheaper, has a hardware FIB and
therefore also does all the MPLS bits and bobs (though don't use that
until 6.10, we're told.)

If I remember rightly a 3920 can't pop-off an S-tag on egress, too.
There's some silly limitation like that.
