Right now, the only option unfortunately is to use Dark Wallet.

If you really need to receive donations from hundreds of people and stealth addresses are not practical yet (they aren't) then you should set up a web site where donors can go to be given a unique donation address.

Alternately you can add to the privacy pollution by giving out a single static donation address. That's a solution that's easy for you and will cause harm to other people in the future, but lots of other people are doing it...
