At the moment I'm using a Launchkey 61 when not using my weighted digital piano. I do also own a Roland VR-09, which by the way is incredibly hackable courtest of Ctrlr and a couple of custom panels. What is pretty cool about the Roland is, in organ mode the keys respond to hair trigger touch like a real B3, so you can do those really fast funky effects. I will probably always return to it for organ, at least until I can afford a real Hammond. The arguments people are making about having a piece of hardware that you just turn on is certainly valid, but they are also comparing to a stock laptop running a general purpose OS, and also, clearly can afford to spend the money. For those of us who are so well off, Zynthian is a project that greatly streamlines things, and encompasses basically everything out there in the Linux audio ecosystem, including Pianoteq, on a Raspberry Pi. They're also just about to release a new version. I've been messing around with them for about a year now and they're the real deal.
