Event booking plugin

I’m looking for a recommended plugin to allow me to have people book for a function.

If we hold a meeting and have 50 positions available, i’d like people to be able to book online and when we reach the 50 positions filled that it does not allow any further bookings. It would also be nice if people could pay any registration fee at the same time.

Can anyone recomend anything they’ve had experience with?

Thanks in advance.
