which rate should i consider as the proper one?

[nimrodlehavi]

not sure if it's the right forum for the question but here goes:
i run www.proxycoins.com - which is p2p bitspend - you can buy anything with bitcoins thru a proxy who buy it for you and receives the bitcoin thru the system escrow
in these interesting days of constant rate changes and hugely different rates, which should be the rate i rely upon in the system?
currently i use the one from blockchain.info but it looks off most of the times...

thanks in advance
