I used to use Wossl and StartSSL before for lots of little personal projects. I recently switched everything over to LE. I am looking forward to switching other projects to it too, such as ones for clients where we had to pay for wildcard certs in the past. Not having to mark the calendar to renew certs every year is going to be really nice.

Incidentally, does anyone have a good way to integrate LE with EC2's load balancers?
