Paypal target meter uses the Paypal NVP API (which means you must have a premium or better account) to display a progress meter of donations towards a monthly or yearly goal. Setup is a breeze, requiring only your Paypal API credentials, and it supports filtering received payments by the email address they were sent to.
You can see a demo of the plugin on the BrainSilo web page at http://brainsilo.org/
