@tomcy6 I quit spinning discs a long time ago and have not followed the equipment nor the market. If you are considering one, and are concerned with that specific dealer’s feedback, I’d reach out to David Schultz / T+A USA ... I’ve found him to be direct and fair about how he positions various T+A components. He might be able to refer you to owners who are okay with being contacted.
Perhaps an owner(s) will offer their own comparative experience here (3000 v. 3100 series).
