Single group Slayers are fairly common in the NW United States among high end home use. A controlling share was acquired a while back by Grupo Cimbali. This may mean wider distribution in European markets where it wont cannibalize other Cimbali brand sales. In the US that typically means highly custom home or cafe environments.
I’ve had some really nice shots from them in both commercial and non-commercial settings. But I think where they stand out now is the ridiculous customization they’ll do in-house.
For BB in makes sense to offer a product at the top end to make sure that if someone has the money, they have the opportunity to spend it.
