well, if you're using 125 gigs more than your plan, I'm sure you're spending lots more than you would with a larger plan anyway
130g/month isn't bad subbing 1 movie freesite a day, depending on how many you already have out there. A virtual plan from Webair with 350 gigs is only $20/month. I don't use that much yet with movie freesites, although I don't do one a day.
just take a look at some of the hosts people use here and see what plans they have - Webair & Colo-Cation are the ones that come to mind first.
