Jason I believe has a GPS4. I have not seen any on eBay in a while. http://www.brandywinecomm.com/literature/bwc_lc_GPS4.pdf
There is also the HP 58540A that looks a lot like the Thunderbolt, but the specs are not nearly as good. I have not seen any of those on eBay in a while either. http://www.realhamradio.com/58540A.htm Then there is the Fury, by Jackson Labs. This one is very new, so I would not hope to find one on eBay, but it is much less expensive than the Thunderbolt as new, and the specs are very good. http://www.jackson-labs.com/docs/Fury_Flyer.pdf Didier KO4BB Richard W.
