This is what I use. No DR but it works great. It doesn't show it in the pictures (or talk about it at all in that particular auction), but it does have a tiny gold MMCX connector on the side of it. I have it mounted in my center console and connected to a 30db gain external antenna. When I travel, I can easily disconnect the antenna, pull the SUG-226 off the hub in my center-console, and then use it with my laptop. I love that thing... super tiny/prtoable, super fast Sirf3 acquisition, and a great internal antenna + external antenna connector.
This also looks interesting.
