Welcome Sparky. I'm glad you found one that works. Is the Vapor King a rebranded KR808D-1? If it is, it is no wonder you like it. Good stuff!
My understanding is that the Vapor King and the Bloog Maxx Fusion are both KR808D-1 based. It was a toss up for me which to get, but then Bloog was out of stock on their big starter kit, so i went with V4L.
I have been telling the guys on the jobsite (I'm in construction) that smoke, that they should check it out. Every one of them seemed genuinely interested and I have directed them here to do their own homework before spending any money, warning them that there is plenty of Junk out there.
