@sb-woo – Just looked at their stock and they currently do not have a carton’s worth of the 400A2. They do have a carton of the 300A2. Those are $92.60 each. I shot an email to the director of sales and marketing to ask when they would have more supply. If not for awhile, would you still be interested in the 300A2? I can post the specs if you are interested.
