I used some RAD T3-FE media converters from 8 years back or so. They had 
really small buffers (just a few ms) so if power usage is not a problem, 
I'd definitely recommend a used 7200 (non-vxr) with NPE-225 and IO-FE and 
a PA-T3. It probably uses 10x more power than the T3-FE converter, but it 
does a much better job of getting the traffic thru in a nice friendly 
manner (fair-queue is really nice).
