I use mine at the beach and find that it is the perfect size for my needs. It is durable and should last for a very long time. It's stainless, so it's not light (and not that heavy), but anything lighter may not have the durability that this one has. The holes seem to be the right size and I have yet to lose anything through them.
I bought an extendable fiberglass handle (made for paint roller) and love it. It was a little bit of a challenge to get it to fit properly due to the larger size of the tubing used on the scoop, but well worth it.
My buddy bought a larger scoop and it's just too big, and too heavy for my liking. He also bought a smaller round scoop and it's way too small to be effective.
