I have had very good luck putting an LH 2.4 ECU from a '90 16-valve N/A in my '89 16-valve turbo after the ECU died. I also pick up LH 2.4 ECUs whenever I find them in the pick-n-pulls and keep one in the car as a spare ... just in case. I believe that any LH 2.4 ECU from any C900 will work in any C900 that uses one. I also have one from an '89 9000 to put in my car as a test when I have time.
So, I'd say get the pick-n-pull ECU, and pick up a spare.
It only takes 20 or 30 minutes to change one out ... probably less time as you develop the technique. Avoid ECUs from '89 900 normally-aspirated 16-valve cars. If the price is right and they are available, pick up a few of them. How much do the pick-n-pull junkyards over there charge for ECUs? Can you get 30-day warranties on them?
The new parts that you will want to put in along with the replacement ECU are new system relay and fuel pump relay. These are located in sockets above the ECU. The anti-feedback circuits in them degrade after time and can allow damage to the solid-state relays in the ECU.
