KHUMO V70! supposed to be very good although not in super soft compound (they wear very very quickly) i have just bought the 235/45/13 khumos from them. they are cheaper than the ones you mentioned also

There are some 195/50/15 R888 for sale on pistonheads at the moment. Not sure if they are far from you.
