I would not mind a Summilux either, but...
After getting back another roll from the Summarit, mounted on the L1: It is going for less than a 50mm F3.5 Elmar these days and a professional cleaning will do wonders for it. At F4 and below, it is very sharp and compares well with my Summicrons. And at under $250 with the CLA, it is some of the cheapest Leica glass going. Close-up and wide-open, it is soft. That makes it fine for portraits.
