Where to find current bandwidth prices across industry?

To aid price negotiations with ISP

[andye]

Hi all,

Does anyone know of any sites that monitor current bandwidth prices for the major co-lo / managed hosting ISPs?

The reason I'm looking for this info is that I'm renegotiating the contract with our current ISP, and I'd like to be able to say "well, your competitors charge this, so...".

Many thanks in advance for your help.

Best wishes,
Andy.
