Thanks everyone so far for your valuable input. It seems the Orion is slightly less expensive than the Celestron, if you get the Celestron discounted (about $140).
I just had a chance to look thru one and it seemed to work well, but I have nothing great (barlow) to compare it with, except comparing a 14mm XW with 2X barlow against a 7mm XW with no barlow. The losses seemed small, but I didn't have a really great night/ seeing conditions to be conclusive. However at F5, the 14XW barlowed, was sharper at the edge of field than it normally is. No surprise there really.
I'm interested in using a barlow on those rare nights for planetary use, and thought the better the barlow, the less it gets in the way of the final image.
I had a chance some time ago to get an old TV 1.8X barlow for a good price. Should have tried it!
When I can be more conclusive about the comparison, I'll give my 2 cents worth,
Clear skies
