Which one Leica lens would you buy on a tight budget

Hello everyone
Hope you all are ok

Around the turn of the year i posted a few photos from my Digilux2.
For various reasons it is no longer with me.
I have today paid for a Nex5.
Funds are low.

I love dreamy out of focus backgrounds and 50-100mm equivalent focal length.
(On my ep1 my most used was zuiko 50/1.8).

If there is a Leica lens under £200 which would you have please.

Thank you.
