Vixen ED130SS, NA130SS, NA140SS?

Anyone used any of these telescopes? Opinions?

I use the NA120SS for DSO photography, and I love it. Compared to my SCT it has far better contrast, flatter field, and the stars are pinpoints. I'm always amazed at how detailed and sharp the slides can be, about as good as from the Nikon lenses I use for widefield. I've taken lots of bad photos, but I've definitely learned it's not this scope's fault.

I wish the focuser was in the same class as the optics, but it's really not that bad. I've thought about upgrading to a Tak or AP focuser, but haven't worked through what that means yet.

There was an NA130 for sale at the same time I got the 120, but I didn't know anything about them and decided to go low, just in case it didn't work out. Now I regret that just a little, but the 120 has been a great scope for me.
