After reading a lot in forums and talking to different people I belief I found a good solution (Thanks Jette!). I actually stay with the insurance I have always been in Germany. They insure me private for a week and give me than the option to become travel insured with their exclusive partner ENVIVAS. I don't have to be insured in Germany during my long term travel, as by law they have to take me back when I apply again for it when coming back. That's a saving of about 1300 Euro. The ENVIVAS cost 0,80 Euro per day, which makes it 135 Euro for 7 month! Plus: As an extra service TKK pays my 230 Euro vaccination costs, even the tropical ones :)
Uhhh... I belief I can do some shopping and get a new jacket :P
