This is cool. However the problem with $65 products like these as a business model, is laser printers, 3-d printers, and gray market Chinese clones at the dollar store. If you run in a very small market with basically no competitors, then no matter what price you select you'll be leaving great piles of cash on the table that someone else is going to want to scoop up. Also their "Products Available on Other Websites" "Concise slide rule No 300" link is dead and should probably be something like this: http://www.concise.co.jp/products/list.php?category_id=31 http://www.concise.co.jp/products/list.php?category_id=31
