Help me select a Service Provider in PA, NJ - I'm in CO and moving

I need help in selecting a service provider.

I'll be living in either Mercer or Bucks County,
working in Mercer county,
personal travel to Philly, Jersey Shore (Mannesquan), North Jersey, CT (Bridgeport), and Albany
business travel to Atlanta and Tallahassee on occasion (but for a solid month to start)

I will be managing a NJ State IT contract and need reliable service to quaterback any system problems which occur. While I get the office set up over the next 2-3 months, it will be my primary work and home phone.

I have thrown out Cingular and Sprint because of service/coverage problems I have heard of. I am considering AT&T, Verizon or perhaps Voicestream (since I can get the Nokia 8260 for $50 at the Sam's Club here in CO). The Verizon phone selection (out here at least) really sucks and I have heard horror stories of their billing and customer service, however, from wehat i have read and heard, they appear to have the best coverage. I have always been very happy with AT&T customer service but a little sceptical of local covreage.

Any input appreciated

Ted

PS, anyone moving out West , DO NOT USE QWEST.
