headlight recommendation for my Duster

Even "stock" Halogen bulbs will be a lot better if you start off with a relay kit.

The Hella conversions are nice, but priced per each, and does not include wiring or relays. I would see if Crackedback is still providing his kits if you aren't much into wiring, and/or lack the terminals and proper tools.
Maybe get crackedback's wiring kit, but pair it with the lights from this kit. It does include wiring and relays, but it is a "generic fit" kit, and the wiring would need to get balled up someplace.
