PCDave,

It all depends how much of a perfectionist you are, how much you want to spend on your engine and what is wrong with it.

You might try to determine what is the cause of the low compression 16 bar (~240 PSI) cylinder. A wet and dry compression test might determine whether it is a leaking valve or leaking piston rings. Valve job is easier and less expensive to repair than piston rings. I don't know if you can get the oil pan off your engine without removing the engine to put in new rings.

As long as you can get it started, which shouldn't be too much trouble with ony one bad cylinder, and it doesn't misfire after warmed up, you could probably drive it as is. If it gets to a point where it misfires when warm, then it needs repairing.
