Laser toner, particularly color laser toner, is every bit as obscenely expensive (more so in raw dollars per purchase) than ink is. That being said, laser toner cartridges are far less expensive on a per page basis than ink cartridges are.
That being said an inkjet printer with a CISS (Continuous Ink Supply System) is less expensive than laser if you buy your ink in large bottles.
One big advantage of laser, though, is the ability of the final printed page to withstand extended exposure to bright light. Laser toner is essentially pure pigment and is highly resistant to fading whereas the dyes used in most inkjet ink (except pigmented black) will fade badly if left in strong sunlight.
