I think that you're loosing site of what this forum is all about, helping other viper owners not thanking sponsors ( and I do wish Jon B the best).
A new viper owner ask a question, got a few replies, including one from JonB, that used this opportunity to plug one of his product( a battery charger), and a couple of other viper owners (me included) pointed out that,if you so desire,other sources exist for cheaper,reliable charger.
No one said not to buy from JonB and I believe that viper owners are smart enough to make their own decision..
"Wonderful. Just a wonderful way to thank the sponsors for the site."
