Hi Laurie,
I have the North Grooup 102mm triplet and am very happy with it.
Side by side with a Vixen 103mm (albeit optimised for AP) it was equal if not marginally superior on Jupiter.
I also got the upgraded AP focuser but I don't think I would bother with that if I were you. Although it works for AP I'm unable to get focus on my longer focal length eyepieces as the focuser doesn't allow the drawtube of the diagonal to sit all the way home. Going to try fixing it but if that fails I'll probably just go for a Moonlite or Feathertouch and be done with it.
