If your looking for a garmin tracking system, I dealt with a GPS4US, there on eBay. I bought a few systems for my self and friends of mine, I contacted them first to see if they could do something about the custom charges from the US to here in Northern Ireland, they explained to me that the import tax is calculated by how much the shipment is worth, so the would mark it down for a lesser value to save on the duty to be paid. I also send them 3 collars back for repair just 2 weeks ago 2 I bought from them and 1 that was out of warranty which I didn't purchase from them. It cost me 17.50 sterli
