If you factor in the exchange rate, you can buy Ethereum cheaper then during the sale through Ethercoin.
Day 1 of Ether sale: 2000 ETH per BTC @ $625 = $0.31 USD per Ether
Last Day of Ether sale: 1337 ETH per BTC @ $475 = $0.36 USD per Ether
Price today through Ethercoin: 1250 ETH per BTC @$375 = $0.30 USD per Ether.
Any FIAT based buyers should take a serious look at Ethercoin as a way to purchase Ethers. ESCROW through John K or other trusted parties is not a problem.
