I have a K&M Matchcase and yes, they are worth the money.  No, let me rephrase that: For what they are, they are insultingly cheap. I would have payed twice their asking price and considered it a bargain. It amazes me that people will pay top dollar ($100+) for a quality knife, and then balk at the paltry price of one of these match cases. 
A 11/2-2" diameter version would be nice, but don't hold your breath.....
