I'm not crazy about this one. Not much search volume for this combo, and global P2P searches way exceeds the US searches, so you are chopping out 2/3 of the market by making it US centric.
Low to mid XX. P2P Europe would have been better, but taken - EuropeP2P.com is available. There are other P2P[country].com combos that are unregistered. If you feel this one has value, you should be going after some of the others.
