CDN locations for US eyeball networks

[john_c.bell at yahoo.com (John Bell)]

Hello NANOGers.

I am in the process of scouting for CDN node 
locations for content delivery to end users in the US. Currently looking
 at Seattle, Los Angeles, Dallas, Chicago, Miami and New York.
Would 
much appreciate any recommendations, best practices or advice on 
how/where to get good connectivity to the large eyeball networks. Being 
small fish, connectivity will be based on the transit I can score or in 
general connectivity that DCs/server providers offer in the locations 
chosen.
