Mirror coating lifetime..

This issue has probably been to death elsewhere but still...

What is the typical lifetime of coatings on mirrors used by Orion or similar scopes. I am curious to know how long people have had a scope and used it before they had to recoat it. Does it make a difference based on standard coatings or enhanced?

Also, would it vary based on usage?

Thanks.
