NY carrier neutral colo: what a maze...

Anyone have recommendations for carrier neutral colo space in NY? Looking for a place where we can cross-connect cheaply to most major carriers across the floor. I guess PAIX @ 111 8th, Telehouse @ 25 Broadway, and maybe S&D @ 111 8th come to mind. It's often difficult to figure out who's available across the floor or meet-me room, vs. who's in the building and thus 6mo & $10k away. Grrr...
Thanks!
