BlackBerry 7130e

I am thinking about getting this phone, because of its email capabilities. The only thing holding me back right now is the expensive data plans. I would be reading and writing emails frequently throughout the day (I do not plan on browsing the internet much on the phone). I will not pay $45 dollars a month for a data plan...too expensive, but I am thinking about getting the $25 data plan. Any suggestions about how much 10MB will get you, as far as email everyday and limited web browsing.

Also, if the 10MB data plan isn't enough, is the unlimited VCAST plan ($15) worth getting to read and write email each day.

Thanks for any suggestions.
