I like being able to visit the grave where my parents and now my brother are buried when I go back to Tipperary. I think it's good to have a place

No need for a big flash coffin. No need for any coffin - follow the custom of some monastic orders, where coffins aren't normally used. Or if there's some city ordinance requiring them (bloody cheek), you can get cardboard ones these days.

If it's got to be cremation, the Indians do it much better, out in the open.
