Bought the passport 8500 x50 for 216.00 plus 35.00 shipping on ebay and would have came with a 3 yr. in store warranty. But I read the other posts from you members and radarbuster.com and quickly canceled the order within a few hours. I learned about the discount from reading the other posts.
I called Radar Roy and asked about discount for being a member on this board and he gave me a promo code for 10% off. I ended up ordering the passport 8500 x50 for 269.00 plus 5.00 for a total of 274.00. So for 25.00, I got the RD from an authorized dealer back with full warrantly.
