Wtb: 20B German Anglo Concertina In Europe

[MatthewVanitas]

I'm going to be staying in Berlin until at least early June, and probably coming back here over the course of the year, so I'd like to have an inexpensive concertina to keep at my girlfriend's place so I have something to play while here.

 

I want to keep it cheap, like in the €100-150 range, and also thought I might as well stick with a German theme and get one of those cheapie Kliegenthal 20b Anglos. Key unimportant, concert pitch unimportant, just something broadly playable and generally in tune with itself would be great. Any of our Euro members have a beater Scholer kicking around that you're not using?
