I bought one of these before knee problems put an end to my running
days. Now I use it every time I take my mule out to the
trails, it is great. I ordered mine on the Internet and paid about
$149. One tip, the batteries usually last me about 8-10 hrs. I
can't imagine being without it now. I believe there are two different
styles, one offers a longer distance in the memory, I think.
