Currently PayPal Express (not PayPla Standard) is broken in UC at the checkout page. This is one of the thread on Drupal.org about it http://drupal.org/node/1211462#comment-5260582
I'm just trying to get a roll call to see if anyone wants to donate and now much they could donate. Longwave gave me a quote of $250 but could be a little more. I can pitch in $150 no problems.
