considering how much money people put in their modulars the moog one is a steal!!! Coming from the Buchla/Serge realm...these prices are not bad whatsoever.
I think we're at a great time of synthesis where hobbyists can afford the high end just as well as the performing musicians can, and across the board you can get things that match your price range. Whether it Boog, 0 coast...etc. The barrier's dropped.
Mid-range synths are still there, look at DSI. I don't think DSI is going anywhere with how used it is.
I do see a scary trend of small companies trying to take on poly synths, I'm terrified of those with the amount of bugs they could have. The River for example, it looks cool and all, but do I trust it's reliability? hell no. The Sunsyn took years to have a stable OS. Modal's OS needed a helluva lot of work too... I hope I don't have the same experience with the Moog I had with the Modals.
