When should I buy LED light bulbs?

Dimmable LED light bulbs seem more economical than halogens. But they're really expensive. Will they quickly come down in price, so I should wait? Or will they come down slowly, so I might as well start saving? Also, how good is the dimming? I tried dimmable CFL's, but they don't seem to dim past 50%.
