The holy grail of Event Management Plugins?

i know similar questions have been asked before, but the answer’s to them don’t quite satisfy my needs, so i’m re-iterating the question:

I’m looking for a modern Event Management plugin with the following criteria:

• simple, WP-like UI (Event Calendar 3 is excellent in that regard)
• uses modern WP functionality like custom post types or post meta
• Events are either posts or a custom post type or at least behave like so
• multiple days per Event (can be a single span over several days)
• Registration Management
• clickable Event List or Event Calendar Widget
• ideally, Paypal Integration
• ideally, Email Notification

I’ve tested a few, but:

• Events Calendar 3 seems to do a lot of things right, but is too basic
• Events Manager Extended looks good, but doesn’t seem to work properly with 3.1 (i get neither the map display nor a registration option to show on frontend)
• WP Events Calendar just feels ages old and overwrites my stylesheet on every update
• Event Espresso Lite looks great in terms of functionality, but the Admin Interface is horrible UI

I also tested ‘Events’ and a few others which were either too simple or had horrible admin interfaces.

Is there anything i haven’t seen, yet that i should have a look at?
