I see a few about but what is better.
Ion do one but the so called quick release will be hard work if in the crap.
LEASHLOCK -- hawiian and available on the internet. Works really well! Arrived 8 days after order - the legrope attachments are great too!

I use that waist belt but have taken to making my own leashes by threading bungee into bunched braided line with a whipped brummel lock splice at each end.
About a 1 tonne breaking strain, a shed load lighter than your usual off-the-shelf coiled rubber leash and about $10 NZD materials cost (plus a small ss shackle).
Because it's braided line probably less prone to failure than a nick-prone rubber leash too.
The trick is to get light bungee cord and the right ratio of braid to bungee based on your standing position relative to the connection point on your board.
Good for racing/flat water. Not enough give for surfing!
One good word for the design work of DJ on the Balin Monster Coil leash.
I just purchased a second one. I use them with a belt and cannot be happier. All the small details that make you forget about the leash and that are super useful and show that the person that made the suggestions know what he is talking about and what is useful.
