I bought a used Cowen uncapper last week and was needing a manual for it. Contacted Cowen, had my credit card handy and was ready to use it. No charge for the book nor postage. My hat's off to them. Obviously I need a book to order parts for the correct number, etc. so why wouldn't they? However, in this day of charging for everything being commonm it's refreshing to deal with someone who seems to want your business and are willing to earn it.
