I recently had two sets of MOCs sent off, the first (from US sellers) to AFA, the second (from the UK) to UKG. Steve at UKG has kept in touch throughout, the whole thing has taken only 3 weeks or so and I know what grades the figures got.
By contrast I have just received my two AFA graded figures, and one has been failed for a reseal on one corner of the bubble. No comms from them at all to inform me of this beforehand. And what really makes me chuckle is that AFA have taken so long that I'm now a week outside of ebay's 45 day window so I have no comeback at all, and I'm at the mercy of the seller taking it back and refunding me (which to be fair he has said he will, but I have no ebay protection).
Bottom line, if you want a decent service, where you know your items are not going to end up in a black hole, use UKG.
