Depends on what you want out of them, off road or highway use, where they will mount and what size you are limited to.
I bought a set of Hella's here:
Hella FF1000 Driving Lights and Pencil Beams and in HID Xenon for just 89. 75 you get 2 + all the wiring. They are pretty amazing. Come standard with 55w bulbs and I won't be upgrading the bulb either.
I mounted them on a Jeep to supplement the high beam and they offer plenty of light IMO especially if you are using them on the road.
I have these
KC's on the truck but have not had time to wire them up yet so we will see about those.
