I use Event Espresso Pro and would give it 5 stars. However this review are for the lite version:
Recently I used Event Espresso Lite to set up an event for a charity fund-raiser. I fully expected fewer features, but was disappointed that the features that were included did not work as expected, and was particularly frustrated with broken or deficient functionality when clicking links in the emails sent from the website by the plugin, and a limit of 50 records on an event's attendee list (a bug, I think).
As I said, the Pro version works great. Looks like there's not too much pride embodied in the Lite version though!
