Well, I took the plunge and bought a revo off ebay recently.

After installing, DAB reception was poor/non existent.

Upgrading the aerial had little effect, eventually I sent the unit back to revo for repair. They were great, and repaired the unit FOC (even though it was an ebay purchase).

The unit now works perfectly, and I would highly recommend.

Its a good work-around for the broken FM seek feature in 2.0 final also
