Quite good, but check out their others first.
The Berlin Phil. under Karajan recorded the Beethoven symphonies three times, in 1963, 1977, and 1984. I used to work in the classical room at Tower Records in Atlanta before that late, lamented chain sunk under the weight of upper-management incompetence, and we always had a whole row of boxes of the 1963 set ("outstanding value for money", in the words of *The Penguin Guide to Compact Discs*) stocked on the shelves. Naturally we kept a copy in the play bin, too; at $35 for the whole set ($30 when a sale was going on), it was a reliable, steady seller. I don't know if it's still available as a budget item (the prices here suggest that it's not), but I would say that if you know you want Karajan conducing Berlin and you're willing to live with the tape hiss, at least give the 1963 recordings a shot before you make a decision.
