Hi George----Welcome! This forum is fantastic for learning things-- it happens each and every time I check this site. People are friendly and very knowledgeable and willing to share their expertise freely. Sometimes the discussions may veer off-course a bit, but for the most part, everyone follows the rules and behaves.
There are rallies all around and they are excellent ways to check out various makes of FGRVs. Since you haven't yet committed to any unit, perhaps you'd enjoy to mingle at a rally
or two to meet and greet the owners and get a better idea of what you'd like.
Again, welcome. We're glad you found us.
