We recently had exactly the opposite experience, unfortunately.  During
relocation of our datacenter we asked our MPLS WAN provider to provide
GigE transport rather than the multiple OC-3s we were using today. To us
it seemed like it would be cheaper - GigE interfaces, even WAN-PHY rated
ones, were orders of magnitude cheaper than SONET.  Unfortunately the
provider came back with absolutely outrageous costs for the port,
claiming they had to do non-standard agreements with incumbents to
provide the lines to us (despite the amount of circuits already in the
site).

This may be more a function of that particular provider, however.
