Just another vote for the JK headlight conversion. They're slightly better than the original, which is nice. They look a little better in my opinion and what I really like is, should they ever burn up a bulb, you just have to replace it from the back instead of pulling the whole bezel out, etc.
I also picked them up off of craigslist, $20 with bulbs in them. Just some $12 jumpers that went from H4 to H13 and I was in business.
Original sealed beam on the left, JK housing on the right.
