This set is lightweight and easy to use. The pushers are connected, which I like because they don't get lost in the bag. Also, the price is right! 

This set is also light weight and easy to use. Again, I like the connected pushers. The bag is made of canvas material, which is a bit stronger than cotton bags. The price is mid range.

This set is a bit heavier to carry due to the wooden racks. The racks pretty and the pusher is detachable. It stays attached to the rack with magnets, a clever design. The bag is cotton and light weight. The price is a bit higher due to the wooden racks.

For when you travel! The tiles are thinner and more light weight than a regular set. Highly recommend!

This is not an Amazon set. It is from Mah Jongg Maven. The tiles are lightweight and the set is also not heavy to carry. Mah Jongg Maven has many customizable options.
