There are several makes of cymbal cases that would work nicely. MOST music shops catering to something other than kids bashing drums should be able to get you what you need. Larger ones may also have a second-hand/consignment area where you could get a decent case and save a little money.

I'd add a little foam rubber against the inside (even if there is a bit already). My road case for my cymbals would work pretty well will a little adaptation (like, removing the center post the cymbals are supposed to be lined up on).

Of course, I prefer to use my drum as a carry-on. Toothbrushes and razor and the like can be gotten ANYWHERE. A good bodhran is a bit harder to find...
