Lee, I'm planning to get the Shipway Mahler 5th, although I haven't been able to borrow it from the over 100 public and college libraries I have access to. I was able to borrow his Shostakovich 10th, and felt confident to get it and recommend it here. Yes, I listened to the Jarvi disc(not the Skrowaczewski)and liked it, but I like the 1981 Karajan a lot and got it.

Enjoy the music, not the equipment.
