As I think I mentioned elsewhere: these people are top-notch. I ordered a 9500 and had them hold it for me until I got back to the USA from India. Later after arriving, I ordered their 4510A wattmeter. Before it came in, they posted on their web-site a special promotion that if you ordered a 9500 you would get the 4510A free. Well, I ordered too early. When the wattmeter arrived, I looked at the invoice and the price was $0. They didn't have to do that, but they now have my unending allegiance. That is a real class act. Now if they would just get the 4040 tuner done and shipped.
