Having picked up a couple cheap recently (#1 and #3, leaving me without #2)I think they aren't bad, the Phoenix mission is drawn very faithfully.
They are a touch expensive I think, ?7 each or 3 for ?20 (festival prices), and you don't get a lot of strip for that, though they do seem to get better as they go on, with more strips, features and articles in there.
Of the three issues, the main story has three 2-page episodes in each issue. The Phoenix Mission doesn't finish in these three. So a bit of a cliff hanger.
If they'd made it into more of a magazine with strips earlier, and not printed on the amazing art paper, they could probably have sold more and then eventually a collected edition on better paper. But they are doing it for the love of it, rather than trying to fleece people (I suspect it was an expensive project).
Not a bad present to get someone who is interested in Dan Dare though!
