well, if I buy a Moog that doesnt mean that I wont buy any Behringer sometime. An If I would be just looking for the cheapest way to make some noise, I would stick to apps. Good design doesnt mean that you have the most features, but that you concentrate on the important ones. All of my moogs sound exceptional good, have great haptics and are fun to play with. They cant do anything, but what they do, they do well. But this the beauty of the synths – there is so much variety that everyone can pick one up that fits to his budget and needs.
Its a bit like drinking red wine: When you start, you think its great to become drunk by a cheap one for 3 bucks a bottle. when you grow older and get more experience, you can appreciate the quality of a good one, even if it costs 20.
