Yes, as I stated in a previous post, that seller has a poor track record of responding to it's customers (or even potential customers). I, and others, will never do business with them for that reason. Have you tried putting some pressure on them by contacting ebay or paypal and complaining directly to them? If it is a recent enough transaction, you can get a phone number and other contact information about your seller from ebay by going to
http://www.ebay.com/sch/ebayadvsearch?_sofindtype=9 and entering the seller's id and your auction number. If you need to get another motor, I would recommend the Stab HH90, HH100 or HH120 (1.2m dishes). Stab is the company that developed the USALS positioning system. They are made in Italy and are very high quality. There are several sellers on ebay who offer them. Good Luck!
