I'm getting ready to check these out also. About a year ago when the markets caused my business to go down one of the first things I did was cancel my wife and daughters cell phones. I was glad to get rid of them because I hate monthly bills. My wife rarely used hers and my daughter always went over her limits. I would like a couple of phones to use when needed but not have the monthly bills.
I hope someone can give us some inside on the pros and cons of the prepaid system.
