I still have my DDM 6000k 35W kit for my low beams. Using Phillips 9011 HIR'* for my high beams. They are great, out here in the country on the hills and back roads. (Along with the Hella fog beams.)
But, I too have a similar problem with my night vision. The contrast helps make the white in the lane markings and in road signs "pop" or glow. And now, with snow all over, it helps see my surroundings when driving at night. Just avoided 2 deer on my way home tonight because of them. I just got a new script and new glasses, which help some, but I don't think I could go back to bulbs with a lower color temp.
I have some spare housings here. I thought about doing the "mini" housings that supposedly fit (with a bit of work) into your opening for the 9006 bulbs. They fit through the hole, and attach with a large nut on the back, and you can run HID bulbs in them with a nice cutoff pattern.
Not in your budget range though. I just don't see it happening for less than $100, maybe even $100 per side.
If you have to drive a long way, maybe just aim the passenger side more toward the center for the time being. Or maybe even switch them, as the driver side tends to shine back across your lane instead of outward.
Another thing to consider, try a HIR bulb (9011 is 65W, I believe), and can be adapted to either the 9006 or 9005 opening, depending on how the one tab is cut. The 65W HIRs are nearly as bright as a 9006 HID as far as output. The color is still yellow in comparison, but its better than your average auto store bulbs.
