Yup, the local provider and their investment/ willingness to upgrade is what really matters.
for techincal reasons, a good cable link will beat a good DSL link, usually higher speed and lower ping times.
Propig the broadband reports link above should have some comments by users in your area, also ask all your neighbors local people using the same providers. That should help you decide. even more than more than raw speed, good, accessable 24/7 tech support is a must. Hopefully you'll never need it.
