T1 provider

hey - our new building can't get DSL (who can?), but it appears the previous
tenant had a T1 line. I'm new to the Phoenix area - can someone give me
some pointers on T1 providers in Phoenix (what does the line generally cost?
etc.)

I really don't want to go down the ISDN road; we might even go for cable if
the T1 is too expensive.

tia,
