personally i would want a phone with android and 4g which is the t-mobile G2 with google and a t-mobile mytouch 4g
but look at those sites to get a feel of what you want.
if you want unlimited talk text and data is is $100/month
the same but with 1500 minutes is 80/month
same with 1000minutes is 90/month, this doesn't make sense
same with 500 minutes is 80/month

personally i think it would be smart to get a family plan
you can get 2 lines with 750 minutes total, unlimited text, unlimited data, free nights and weekend, free mobile to mobile for only $140/month
then you can add upto 3 more lines for $10 a piece. i assume they would also get the same sh*t, but you have to share the minutes.
but unlimited talk, text and data for a family of 2 is $180/month, get 2 more people and that is $200/month or $50 a person.
