I love the classic Korg sounds and have used a lot of their gear (M1,Trinity Plus, X5d , N264) and I currently have an X50 at home , but for my gigs I bought a Juno Di and Fantom XA from Roland , and by using korg samples on the XA I have the best of both worlds, including sounds from the DX7, D-50, Technics organ, and SQ80 , you´ve gotta buy what´s best for you.
