Best foldable pull along trolley/wagon?

[LiveLifeToTheFull2]

I'm after recommendations for decent sturdy but reasonably priced pull along beach/festival camping trolley/wagons please?
Thanks!

Timber Ridge is a good brand for these.

We have a Sekey wagon, I really love it. It's huge with deep sides and big chunky wheels. We have three young children and all can ride inside with plenty of room to spare. We bought it to use primarily on Center Parcs type holidays and can unload our car and get all our luggage for a family of five up to our accommodation in just two trips.

We got ours in Costco years ago, it's still going strong
