It was about the same price as the other ones (~$150). It is very small, about 1.5" x 1.5". It worked fine, although the cable for it is highly specialized and hard to find. I think that all the GPS modules are going to give you about the same accuracy. Alex -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
