Bitcoinmarket.com provides great service, it's a good alternative to Coinpal.
Just beware, if you are a seller, your bitcoins get "frozen" while the deal goes through.
Now you are in the buyers hands and it's up to them to complete (send payment) the transaction.
There is nothing that can make them keep their promise.
Problem is your money (bitcoins), stay frozen until they pay. So you can miss a good opportunity to sell them to someone else. You know how sensitive bitcoin market is.
It seems Bitcoinmarket.com's prices are a bit lower than the usual going rate, which kinda sucks for those who are selling.
I want coinpal back :[
