What is the best industrial printer to print leaflets, self-adhesive labels and brochures?

Our design company wants to branch out into doing our own printing in-house but we are unsure of what the best make of printer is. We would be printing business cards, leaflets, brochures, posters and self adhesive labels in digital format. Does anyone have any advice of an industrail printer that would meet all these requirements? Any info would be helpful, thanks.
