I finally broke down and got one myself after the last ice storm left me without a landline for a week.
I went cheap minus the bells and whistles. I bought a $15 Motorola Tracphone. I bought 600 prepaid minutes for about $100 that are good till may of 08. In nearly 2 months I've used less than an hour but I'm pretty satisfied with it. It will come in handy in an emergency.
I don't use my phone much so I have prepaid as well. We use Virgin prepaid because we only have to add $20 per quarter to maintain the service and the minutes never expire. I run my phone for $80 per year.
