I just wanted to mention something I saw in the post about ISO 9000, don't be fooled by this at all. I am a former ISO inspector and thats all that any of the ISO 9000 or 14,000 series means is that the company does what they say they do. Confusing, yes, to put it simply, if a company made cement boots and had a written procedure on how they made the cememt boots, and followed it to a "T", they could get ISO certification. Any business that has a specific procedure and follows it, qualifies if they pass the audit. So it doesn't mean you get better quality anything, it's just a bragging right, so don't let that ever sway your decision on a purchase.
