Providing you can find one in serviceable condition at a price that is anything other than ridiculous quite frankly.
I had an original minimoog a few years ago which developed a triggering problem and would drift in and out of tune over a few hours. The Voyager was an obvious solution, so I decided to buy one whilst retaining the mini so I would have the option of keeping both if I felt it worthwhile. Whilst there are subtle differences in sound between the two, I did not consider at any point that the mm was superior in sound to the voyager in any respect. Sorry if this view is not shared by some on here, but it is my view that the Voyager is every bit as good as the original and capable of a range of sounds that the original could only dream about. Add in the 800 plus memories and after a short warm up, very stable oscillators, it is a beautifully crafted hand built instrument and deserves not to be constantly compared to its ancestor.
You can also pick one up second hand for half of the price of a mm.
Needless to say I no longer have my mm. No contest IMHO.
I found this quite interesting. The tron is fake but he doesn't say what he is using. As he says the mellotron makes a great stand for a minimoog!
I think the Minimoog is probably the only vintage keyboard I could be tempted to buy. The modern moogs just don't excite me.
