At the moment the most popular downlighters are mains powered GU10 leds and the easiest dimmer to fit is varilight v-pro. The v-pro has several modes and you can adjust the low and high point. You can buy them as a separate module and retro fit them in your existing dimmer switches to save a little money.
You also need to check the height of the ceiling space as there is no real standard size for downlighters. Downlight.co.uk is a good source for quality units, avoid B&Q etc they will just make your job harder.
I was basing my post on the horror of the job some bloke did in my parents bathroom. MR16 with an overloaded converter leading to flickering and dead bulbs.
