For a moment there CrowdTilt had me really excited, but then I came across:

1) Need to be in the US and have a US bank account

2) Need to be on Facebook

I'm weeks away from starting a £25k funding round by tapping up my users (who have been badgering me to do this for the longest time).

The biggest issue I've got is that I'm in the UK.

I dislike that the most cost effective and convenient way to do this is to use PayPal and build my own front-end.

PayPal.

I want to use Kickstarter, or Crowdtilt, or Stripe (if I have to build my own front-end). Anything but PayPal.

PayPal it looks set to be though. I can't find another <4% method of doing this if you're not in the USA.

If anyone knows a UK or EU based crowdfunding solution with fees 4% or lower, then I'd love to hear about it.
