the vacuum adjuster is a VERY nice feature to have. i recently added it to my euros. it's the frosting on the cake.
i'd just get those euros you mentioned, all you'll have to probably do is adjust them up [raise them]. they must be bosch to have the vacuum feature.
hook up the "city lights". they are pretty nice.
if you upgrade your wiring and add relays you can go with higher wattage bulbs.
let us know what you do and post a picture when you get them in.
