He states above "looking to get some 6500's".

I would advice against getting 6500 and instead getting 7600 if purchased 
new from Cisco, due to the 7600 BU not allowing SR to be run on 6500 
chassis. With 7600 you have both options.

Yes, SXF is very mature, but if he's looking to go brand new I think it 
would be a very bad not to advice to at least check up on 7600 and SR 
before making the decision.
