There are quite a number of Sony box sets appearing, either good value from amazon, or sometimes significantly cheaper from amazon marketplace sellers. This one looks good - http://www.amazon.co.uk/Bruckner-Sym...=pd_sim_m_h__3 - Bruckner/Wand.
Other similar boxes include artists such as Munch, Reiner, Szell, Heifetz. Follow the links to similar items and browse around.
Perhaps these are better starting points for such browsing
