You wouldn't want to know how much a new ECU from the dealer costs, anyway.
I've heard it's over $1000?

>1.  Is it really the ECU or could there be another problem?

There's 95% chance it's something other than the ECU. It's just that most
mechanics tend to immediately blame the ECU when they get puzzled
diagnosing the problem. Have you or your mechanic checked the error codes?

>2. Can the ECU be repaired 

In theory, yes. In real life, I don't know.

There are no aftermarket drop-in replacements.
