What's the best nokia mobile for this price?

I need a mobile phone but I have only $100 for mobile phone. So please tell me what is the best Nokia set for me which has more facilities?

the phones can be pretty cheap by themselves; I went through one cell phone company and was able to get a camera phone for $1. where you're going to have to watch in terms of price is your plan for your phone (which is why they make the phones so affordable, to jack up the price of the plan) because having service combined with however many minutes you want and long distance and text messaging and all that stuff adds up.
