I use an el cheapo $66 SE phone.
I figure that since I only use the voice call and messaging
functions 99% of the time, I don't see the need for all the bells
and whistles like MP3 player, camera, etc.
It's been a few months since I got it.... and I still don't miss
the bells and whistles. 
Actually I wonder what is the cheapest phone on the market with a
simple camera
I can live without the bells and whistles but I need a basic
camera at least coz it's so helpful
