I remember someone asking John Moss about the difference. The blues are indeed 'shop test' units. These aren't necessarily rebuilt - they are customer return units. If it was well and truly dead, it would be trashed. I doubt the DI manufacturer would rebuild them. Maybe the unit was flaky, maybe it was just fine. But Saab found itself with a bunch of DI's that it didn't want to put into customer cars. So they paint them blue, drill a hole so you can hang it from a hook, and send it out to the shops.
As far as I'm concerned, a used DI is a used DI. A blue one may be a perfectly fine unit that got replaced while trying to track down a problem. A blue one might also have problems at high temperature, or after long runs. A red one might be just fine, or it may have come out of a car that was having problems, and it never made it back to Saab for the blue paint treatment. Used parts is used parts, you take your chances.
If I were buying it from a reputable place where you could return it if it doesn't work, I wouldn't care if it had stripes. If the place doesn't let you return parts that don't work, I wouldn't care if they swore that Thor himself had built it just last week.
The difference in DI's is the connector. Some had pigtail cables (wire comes out of the DI, and connects into the car harness), some had connectors (DI has a connector, and there is a cable connecting it into the car's harness. Older cars can use the newer DI by getting the DI and the cable. Newer cars really want the newer DI to avoid having to re-wire. Saabs attitude is that at some point in time they stock the newer DIs', and those fit new cars, and old cars with the cable.
