Flatbeds, for cutting, no. But Hybrids for printing onto rigid substrates, yes.
Meanwhile, specifics by product / manufacturer is not something I'm premitted to share, pubicly. But indeed, we sell many printers, but far more cutters. I'd venture to guess that more Vinyl Express-branded vinyl cutters are in use, worldwide, than any other cutter made. But data on that is pretty tough to establish, conclusively, since we're not the only ones keeping our cards near to our chest.
But no matter, since for our customers, the only cutter or printer that matters is their own. Our unit volume merely assures they get great value initially; and that the product's longevity (support / parts / third-party add-ons) is enhanced when products are and remain popular.
All my best,
Jim
