Dave, if you end up buying them from
ebay, may I advise you to buy them from an outfit that operates under several names (mit_63 is one of them) but always shows up as shipping from Upper Saddle River, New Jersey? I mention this mostly because there were some fairly serious quality problems with the 6S pages for a while; Lighthouse/Leuchtturm corrected the problem, but some of the defective ones have been floating around on
ebay for a while. I've purchased most of my various from Bernie in Upper Saddle River and have never gotten a bad one.
If you can find any used, that's great.
