I think you will be very satisfied with DCC. It should not be too hard to convert your older units to DCC. Sound may be another story. Keep in mind that not every unit need have sound. I have found that even one sound equipped unit in a consist is very convincing and satisfying. If you have 2 or 3 units in a consist with sound it can become somewhat irritating.
