Bandwidth?

I know this really isn't a correct list, but I know most of you have experience in getting hosting, etc and you have been very helpful in my PHP troubles, so maybe you can help me here, too! :) Anyway, my site is currently colocated at a small ISP, that charges as follows: $265 - 2U rackspace + 8 GB traffic +$8 each GB over 8 I just got my invoice for June, totaled at $947. That's 77 GB over my alloted 8 GB. The site is growing and is very popular, so I am not questioning the bandwidth number, but I am asking about the bandwidth rate. Is $8/GB too much? Last I checked most hosting providers charge by how much continuous bandwidth I use, for instance 512 kbps, 768 kbps, 1.5 mbps, etc. What kind of numbers can you all give me for comparison? I want to see if I am getting ripped off.... Ryan Shrout http://www.amdmb.com/
