Go for it!
I've just ordered 2 tickets for Frankfurt, A4, row 9 for 106 € each.
Take a look here for the "Frankfurt-Saalplan":

www.eventim.de]
There are still a lot of 106 € tickets left.
You will see your places just after you have finished your order under "mein eventim/Bestellhistorie" so there is a little risk but i worked for me and some others as well.
Good luck!
