Well said, Mike & oldnrusty, in your last posts
Oldnrusty: keep reading regarding making a decision on which kit to buy. Most members on the site have the JTR kit. The Scarab, MSA, and John's kits fall in line in that order. If you can, at least buy the JTR manual. It's worth the money, will probably save you some real hassles, and you can always sell it to someone on this site if you want.
Good luck with your swap and you are correct: "there is nothing new under the sun."
