Indeed, having that backup has been worthwhile for you.

I do like your Web page, and added a pointer to it from mine - I made a 
FreeBSD write-up here:


When I bought my second GPS 18 LVC I got the X version (GPS 18x LVC) which 
is a lot more sensitive and allows better indoor operation - you may like 
to add that to your page where you say the GPS 18 LVC is now obsolete.
