Testing QoS generally requires highly specialized equipment that can send at
line-rate and has highly accurate timing.  This is necessary to analyze the
impacts of latency and jitter, in addition to testing the impact of
throughput in multi-queue prioritization tests.  Likely this means that the
cheaper options are not sufficient unfortunately, and doubly so because you
want 10Gbps.

I have used Spirent, Ixia, and Agilent boxes with great success, especially
in the area of QoS testing.  Any one of these should be able to perform well
with all of the requirements stated above.  Don't go for the Breakingpoint
box unless you enjoy banging your head against the wall when you can't do
many of the things they claim to be able to do - I was once a proponent of
theirs until I really got under the hood, save yourself the headache and
look at the other alternatives.
