Sweet or savoury courgette muffins?

[TickledYonion]

I've got some courgettes to use up and fancy making muffins with them. Has anyone got a good recipe? Also do you think savoury or sweet are nicer? I can't decide which to do.
Thanks

I made some courgette bread the other week and it was actually rather tasty.

Sweet!

Well I decided to make courgette brownies and am not impressed. They look good and smell good and have a decent texture but taste of not very much.
