Ok, I gave up waiting for something better and ordered one (elektor.de had a "sale", actually is still up even if it says up to 30th of October, not a fantastic price at 120euro+5 shipping but probably the best this side of the pond). Engineering/development seems to be almost dead but unless and until something better is available I'll try to use what is (I just hope it still works with the next update on my phone...).
