Well, there's three things that would explain the price difference for a DI. First of all 11 years ago most stuff was cheaper, secondly we devalued our currency in the UK by 20% in the past 2 years so imported items cost 20% more. Third, Saab were discounting the price of the DI back then as they'd had a huge number of failures and they didn't want to charge too much. I'd say £250 is quite competitive now for a complicated part that was £150 11 years ago.
