After being asked by dozens of Bitcoin fans, we built a Bitcoin payment gateway for the IgnitionDeck crowdfunding plugin:
http://ignitiondeck.com/id/bitcoin-crowdfunding/. It runs on WordPress and is self-hosted, in the event you want to customize your campaign.
Right now we're using the Blockchain API to convert currency into Bitcoin and to manage the payment tracking, but I'd be curious to hear which wallets and/or Bitcoin commerce solutions you trust/use most?
I've been playing with Coinbase, which I also like, but it seems very young.
