No regrets so far. When I've culled the herd, I've always gotten some satisfaction, giving pipes to active duty military overseas or trading them for store credit, pipes I wasn't smoking traded for credit on a pipes I carefully selected and smoke a lot. I've never outright trashed a pipe, always feeling I got more out of them donating, gifting, or trading for store credit. One group I gave to a friend, former Lucky Strike chain smoker, who wanted them for decor rather than smoking, which sounded okay for his first house ever.
I like the Meerschaum. If it is your only Meerschaum, I'd keep it. Otherwise, it's just a question of how often you will smoke it.
