It's been discontinued? You sure? Epi just released a new multi-model line [including a WildKat, a Les Paul, and 2 ES-types (Casino, etc.)], each called the Royale:
At any rate, I don't have any direct experience with the double-HB (one a mini) AlleyKat. I found a WildKat (the P-90 model that has a Bigsby trem) in a local pawn for 3 Benjamins, no case. In general I have been very happy with it, although the Bigsby spring is stiff and the guitar probably needs a roller bridge to hold tune better. I don't really use the Bigsby enough to have warranted replacing the bridge or trem spring to date, and these should not be issues with the non-Bigsby'd AlleyKat.
Fwiw, ymmv. I have an online friend who had an AlleyKat and eventually had some weird wood separation thing go on with his, but honestly despite him posting pix I could never tell exactly what was going on with the guitar.
That's all I got. Good luck!
