I used Hella H4s for the "big" headlights and Hella H1s for the little ones. The H1s are not yellow so there is a slight change in appearance (which I like). The H1s end up being "driving lights" instead of "fog lights."

The Hella beams have a flatter outside surface so it is easier to install X-Pel (protective plastic covering for glass and painted surfaces -- protects the lenses from rock chips).

Hella beams are not DOT approved but they don't look "modified" so it is unlikely that anyone would object. I stayed with the standard wattage bulbs and a 123 Mercedes is unlikely to be a suspect anyway, right? The Hella beams are so much more efficient that you really don't need more Watts.

With the standard bulbs you can use the stock wiring. If you change to 100 Watt bulbs or rewire so that all the filaments come on at once, you should add relays to take the load without burning something up.

I got my H4s (7 inch diameter) from Susquehanna Motor Sports in Fleetwood, PA in August 2007 for $72 a pair including the 60/55 Watt bulbs.

The H1s (5.75 inch diameter) came from Adirondack Auto Brokers in Halfmoon, NY (September 2007, $116 a pair).

You may be able to do better pricewise, those sources are what I found when I went shopping. Lots of folks sell the H4s, the H1s took a little more looking around.
