Alternative To RAPIDSWITCH - Or Any Provider With Burst Bandwith Beyond 100mbit

I have specific request.

I have client that use around 6-8 TB per month of traffic (nothing unusual really).

The issue is that, at some short hours per week (twice or less per week) - burst goes to 90 Mbit. So basicly, I need a solution, where in near future, if need it - burst can go all the way up to 130-150 Mbit when need it.
Any Gbit providers I seen, they usual say like speed will be around 80mbit or so - and that makes no difference.

I did check RAPIDSWITCH, and in all aspect they ar great (nothing
to complain) - but the offer they have with 10TB data, is good only unless you pass 10TB at some point.

After that, 1 TB of data is $200 or so (depens on exchange rate of $).

At the moment, 10TB of data transfer should be enough but if by some chance, it goes beyond that, it will incresse the cost alot.

Hosted content is pure FLV files, normal videos, nothing special.

My budget is in normal range, but still the less is better.

I will take any suggestion on this, or if someone can push me in some direction (company or point of contat).
