Need Code reader for 94 Subaru SVX

Hi, my nae is Patti. I tried really hard to give you some money, but my paypal account just shut down due to the fact that I couldn't remember my info and I struck out three times.
If you can answer this question -I promise to come back and donate!
I have to set you up here.
I was going to buy a code reader for my other half Ben's birthday. He's a former Subaru dealership mechanic.
The car in question is a '94 Subaru SVX.
I cannot find a code scanner for it anywhere. The Subaru scanner is called a 'select monitor', and they sell them, but the price is thousands and I need under 200. I'd like both OBD I and OBD II for including other cars.
All the Japanese scanners I found do everything BUT Subarus, and the Subaru scanners do everything BUT the SVX. Someone must have made an aftermarket scanner for the pre-96 cars. So their own mechanics could work on them. I'll cross my fingers that you have that elusive answer. Thanks a million, :) Patti
