There are two keyboards I'm particularly interested in getting:

Roland VR-760
This is three keyboards in one, including an organ module which emulates a Hammond B-3, a piano module with great-quality (or so I've read) samples and a synth module which doesn't sound as good as a full synth but that's why I also want to get a Moog (see below).

Moog Little Phatty
This one's a more modern version of the MiniMoog Model D as used by Rick Wright, most notably on Shine On You Crazy Diamond. From what I gather, it does exactly the same thing, only with new features such as digitally stored presets so you can access favourite sounds easily, although the tone generation is still fully analogue.
Moog Website's page (where you can listen to the samples, I recommend skipping to "02 Snappy Lead - Eric Frampton" - my personal favourite)

The keyboard I'm currently using is nowhere near as good as either of the two above - it's called Medeli MC-300A, although Medeli has recently stopped producing it so I can't link to it on their site.

I have a question for anyone who knows much about Hammond organs: are the new digital tonewheel generator and digital Leslie as good as real tonewheels and Leslies?
