700 bucks is a fair amount for a phone that will no doubt be outdated in 6 months from the purchase date.
I bought a sony k700i in july for $850 USD and its already way out of date.
Go with what advise is mentioned above - cheap phones do the same job regardless, you won't get better reception with the higher price tag. As long as its tri-band and has a sweet zoom lens for those times you are 2 steps below a hottie on the mall esculators you'll be fine
