I have a Malachy kearns one but mostly Caroline used tunable one and Malachy's aren't (at least not mine). They look nice but the tunable ones have thicker skin and a softer, more mellow sound so if I was to buy a new one and take it up again I'd definitely go for a tunable one!!
The regular (non tunable) ones are fine in Ireland, cause it's always damp and humid, but it's a bit of a disaster in a hot country or where the air is dry. I keep mine in Sweden in my parents' house and in winter with the heating etc. the air gets really dry and the skin of the bodhran gets really, really stiff and the sound is really hard, I was almost afraid it'd break. Had to bring it into the bathroom with shower on to "steam it". Was not happy with it!
But it depends on where you live and you can get certain conditioner for the skin and steam it and stuff. I'd still say go tuneable, they sound nicer! But that's just me
