usagsm=pretty worthless, GSM isn't widely used in the US as it is Europe
houseitem=$10 to $15
hostingbuy=not a very fortunate choice of words there, ~$15
dnagenetic= has potential, maybe would have been better with a "s" at the end (dnagenetics), so ~$20
USAGSM might be worth more soon, expically since alot of new phones are coming with Sim cards, or maybe could get used for one of those "cell phone hacking sites." If it were developed with alot of traffic, it could go for more than baught value.
