1st Leica Purchase!

Greetings all, I've just purchased a Leica M9-P and was trying to get advise as to my first 35mm lense. I'm looking at the Summilux FLE but it's hard to find and a lot higher in price. Would it be that "big of a compromise" to go with the Summicron?

Appreciate the advice and as soon as I redeploy I'll start posting pictures!
