I found and joined SOS, after buying my plastic speedster.
I did not join to justify or second guess what I purchased. I never even thought of joining a group until I started working on my purchase. Never hurts(IMHO) to ask what others would do and how they would do it. You find out soon enough who knows what they are talking about and those that think they know what thier talking about.
One has to make up their own mind and go for it, why does anyone need others to reinforce or second guess your decision.
What I think might be a great deal, others might think it's the worst deal possible. Who cares.
It is sad, but their are many people in this world that their only point in life is putting other people down. Listen to people you can trust, limited on forums, I'm sad to say.
Point about some forum experts.
I own a camper and had joined a group of what at first would appear of like owners.
One day a person ask a question about coach batteries. A forum member with (75,000+) post responded with lead (the metal) is a non conductor and should never be used as a part in an electrical system.
When someone pointed out that error, they responded with, "I looked it up on the internet and that's what it said". Another internet expert passing information from another internet expert, right, no.
IMHO When you want something, only you can make up your mind.
