cell phone plan

What do you find better, pay as you go or contract plan for your cell? We had a contract for our cells for a couple of years and it was a real pain, you never knew what your bill would be and it really got up there sometimes, average for the 2 phones would be 100+ a month. We decided to switch to a pre-paid phone and now it costs us $25 a month for our 2 phones. Even with cutting our contract phones to emergency service and leaving them in a drawer at home, which costs us $40 a month until the contract is up it is still only $65. We haven't run out of minutes on our new phones once since getting them for Christmas so I feel it is well worth it to have them.
