I can't believe that with 45 comments, no one has mentioned BlockChain.info or other "zero-trust" solutions like Electrum. That way your "funds" are in the BitCoin block chain, and no person, website or service provider can steal them from you, as long as you're certain of the security of the environment you're entering your key in. These solutions rely on you only ever using your private key to sign things OFFLINE, and then reconnecting to perform the action you signed for. BlockChain.info provides an implementation in Javascript; there are also other lightweight clients like Electrum. The steps BlockChain has gone to to allow you to verify, (with the open-source Javascript Verifier Chrome/FF/etc plugin that checks the page js to the github page), that the client-side code is secure, is frankly kind of inspiring.
