I'm waiting to get a shipping quote on the Panoptic 24, so I've locked that in.
As for the 13/14, its a toss up between the Nagler 13 and the Denk 14. I have pm'd Suzy to get her thoughts as I just found her posts regarding her considerations of these two eyepieces. It looks like she went with the Denk14 in the end, but I can't see any comments on what she thought of it.
The Exlpore Scientific look impressive and get great reviews. I am thinking though the size of them may be an issue in a 10" manual dob. It does have tension control but even so. As Graham pointed out, sticking to one size format may be better and the other eyepieces are alot more compact. Down the track since I was also looking at UHC filters for her, again sticking to the one size will mean only having to get one size of filters rather than two.
Again, thanks for your help.
