If you are going to buy one of these things it would be a good idea to find out who makes it (is it American made or did it come from China).

You wouldn’t want it to fall apart on you. Not that you would know. Which invites shoddy workmanship, because after all it only needs to hold together until it’s in the ground.

Mythbusters did a "buried alive" show where they found that even well-built coffins sometimes collapsed under the weight of the ground on top of them.

Even cremation urns cost several hundred dollars and up. My wife's urn was handmade by a potter I know and trust to do a good job, and she charged a reasonable price.
