Hmmm... I'm getting a sense that most agree any of the offerings from GSO, Pentax etc should be OK, and keep in the range of 10-ish to 30-ish mm (150x to 50x). This is my feeling as well.
I think I'll start with these:

If I'm happy with them I'll add more as I feel the need.
You'se have all been most helpful and I thank you'se.
I'll post a First Light report as soon as I can. If this flamin' rain ever stops! Grrrrrrr!
