Why would you get one (over a inkjet) and how much do they cost to run?
Laser: IIRC 'ink' is transferred on to paper by first inducing a charge within the paper before the the paper passes over a roller coated in pigment. Where the paper is charged, the pigment attaches. The pigment is then fixed by heating. Colour is created through CMYK rollers.
Why would you get one over inkjet? low maintenance, lots of output is possible before replenishing pigment, fast (well, some are), in theory more consistent. Why wouldn't you? Bigger, more expensive, not sure if cost per page is lower than ink-jet, when replenishing you feel like you are throwing half the printer away as the rollers can be integrated into the cartridges.
How much do they cost to run? Varies. Big manufacturers like HP should detailed cost per page. You need to be slightly careful with the 'home' laser printers as they tend to ship with lower capacity cartridges; they play the usual sell it cheap, make money on consumables game that they do with ink-jets.
