need router advice please

I need router advice.

my isp is very soon going to limits on how much you can download. So what i need is a wireless router for gaming on pc and ps3 and xbox360 plus bandwidth info such as how much you download and upload and a way to set a limit for speed or amount downloaded. i need to say once x amount is downloaded then speed will be x and to email me when I reach x amount or stop working when x is met. I know that nothing like this is in anything from dlink linksys or netgear that i know of which sucks.

i also would need AV protection, content filter which is selecting from a list of categories to block porn etc.

I'm not rich so this would have to be something for home users.

Well, if your ISP is going to limit bandwith and/or how much you can download I dont see how a router is going to help, you'll still be limited to a certain amount, regardless how divided the bandwith it. If you just need a wireless router to setup all those devices and also get some bandwidth info thats a different story, but if you looking for a router to help increase your bandwidth or hide how much your using, your looking for the wrong device.
