I use Daopay, and they've worked fine for me in the past few months. It's true, I only end up with a certain percent of the profits, but as it's just an alternative to people who can't pay with other methods, it's fine with me.
Also, you can try something I've done. Increase the rates they'll pay with Daopay. For instance, via Paypal, they donate to me for $10, via Daopay, I changed that to $15.
After taxes and conversions and the euro sinking, I end up with less than I would with Paypal. But it's not Paypal - it's an alternative for people that can't use it.
