Webcam for polarized solar filter?

In looking for a webcam that would be sufficient for the upcoming Venus transit. I have a 10" Newtonian on a dobsonian mount. I need something that can take many pictures per second as I currently don't have an equatorial mount. I'm looking for anything from under $100 to $250 or slightly above. I obviously want something that will work well and can be modified to work with a telescope. I'm completely ignorant to this so any help or extra advice is much appreciated.

Thanks.
