Yes I agree with you.
LED will be the No.1 Choice for you.
Usually 7W LED can be the replacement for 50W halogen, so you can see it will save almost 70% of the energy---That's a lot of money.
Also, you maybe say that the price for LED is high, but think about the life time of it, some of then, in a middle class level of quality, can be 60000 hours.
