My experience has been if issues occur they arrange a courier to pick up without hassle. A 'refurb' obviously has a slight degree of risk, but on the flip side it is a lot cheaper.
Yes, it is annoying - doubly so since anyone interested who's actually listened to DRM or other low-bitrate AAC sources knows it's misleading at best.
For the record, the Radio Vaticana broadcast received was ~14.5kbps data rate, ~14kbps audio data rate, AAC+ (i.e. HE-AACv1 mono). Sub-FM quality by a long way. Even if they'd used xHE-AAC, it'd still be mono (since it's below the 16kbps cutoff for PS) with a perceived quality comparable to HE-AACv2 @ ~28kbps.
