The Excelis Saga. What are your thoughts?

In order?

1. Yes, I think they're worth exploring.
2. Excelis Decays for me, but then I've always had a soft spot for Craig Hinton and Excelis's final fate is suitably grim.
3. They each have a very distinctive flavour to them, Dawns is flippant and Decays very much isn't. I'd treat them a lot like the Peladon stories, expect change but not as much continuity between releases as you might think.

Rather odd, I just posted last night how much I love these and that they get so little attention.

Yes, just get them ready to go. It's very much like The Ark where The Doctor sees events in one place from different points in history and with the balance of power shifting enormously. Dawns is very much one of my favourite BF releases. Auntie Iris has a lovely moment consoling The Doctor over Adric, for one. But I won't say too much on the plots as they're not toooo related outside of the recurring antagonist. In many ways this series is the pecursor to the BF trilogies we get now with a story for 5, 6 and 7.  What's great is that each has a very different feel and a very different tone but all make equal sense given where Excelis is at that point. They picked the right Doc for each point as well, but I don't want to get too spoiler-y.

The Benny one is good but it's more an appendice to the story, and a follow on to the first more than the others. 

yeah they are all ok, but its such a long time since I heard them not sure I am the best person to recommend them.

if I remember rightly iris was with 5th doc which I found a bit trouble, and 7th docs ending was a bit grim and not to my taste.

I cannot remember anything at all about the benny one, which makes me think I might not have even listened to it.

but a good set to take on a long journey as they really are 4 separate tales

I suppose it might be a Craig Hinton thing but it bothers me Excelis Decays isn't available for DL.

This series has a special place, if only because it saw Katy Manning returning to do new Who (and introduced Iris Wildthyme to Big Finish). Consequently, Excelis Dawns is my favourite of the four. As has been mentioned, they each have a different feel. Don't skip The Plague Herds of Excelis, as it rounds off the series by anchoring the two ends by Iris and the artefact.

I recall being somewhat puzzled by how the three Doctor ones were supposed to be connected (or whether the series was, simply, three unconnected visits to the same place at different times), but it's been quite a while since I listened.

Safe travels Simon

I'm still waiting for the 7th to be download available before I get these. I keep hearing amazing things about this set though.

I have a signed copy of the music disc by the composer. It's a great CD. Worth getting.
