Not really given the highly integrated nature of laser manufacturers where they bundle the table, drives, CNC, material handling, power supply, and (often) SLA together. Additionally there is a lower run-rate of consumables in comparison to other industrial cutting technologies so the life-time cost is more comparable to competing technologies.

So why not always use laser? They have far higher upfront costs as their business model is not consumable-driven. Further they are limited in material thickness and finish they can handle. They are great at cutting sheet and thin (<= 1/4") metals, when the surface is clean and uniform as mentioned above, but if your shop needs the ability to cut thicker materials or the up-front cost is too high then plasma, oxy-fuel, or (possibly) waterjet are better options.
