I have both Luminar 4 and NEO. Both are unique in their own way. For user reviews see Photofocus (../LUMINAR NEO/LuminarNeo What's new and what's missing-Photofocus.htm). I can identify with many of the complaints provided however, I use both pieces of software (Luminar and others) when needed.

You should not have any problems contacting the the Chamber of Commerce in Reykjavik, for the support you desire.
(My wife and I(and friends), will be taking our second trip to Iceland, July 4th and again early next year).
