I've dealt with Daniel Stern on a dozen or so purchases for 4 Jeeps over the past 6 years and never had a problem. He's a little slow to respond sometimes, but it's always for a legitimate reason (vacation, family illness, etc). Be patient and he'll respond. Your e-mail may be spam blocked and he's not getting it. Try a different e-mail address, if you have one, preferably from a private domain (i.e. not gmail or yahoo).
I purchased the Wipac (British) headlights with wiring harness for my JK and love them. They are similar to the Cibie's but have a deflector hood on the bulb to reduce glare in wet or foggy conditions. The Marchal's were too expensive and didn't offer any improvement in performance. In fact, I'm about to purchase some yellow fog light Oscars from him. I'll mention you to him if I get a hold of him before you do.
