Thanks for the feedback Mick.
Another option I forgot to throw in, is to try and find (2nd hand) the 4.7mm and 6.7mm versions (and maybe also the 8.8mm) of the Meade s4000 UWA. For no other reason than it'd be nice to have a set (to go with my 14mm), and they're the right focal length, and i've read reviews that say they're a good eyepiece.
Astro_south wouldn't sell me his 4.7mm
, and they rarely pop up on the 2nd hand market so it could be a long time waiting for those.
