[DVBC] Features for a GPS for a bike

[dreamer at craftech.com]

Okay, here I go again.  I'm thinking of maybe getting a GPS for my bike. 
I'm not saying I'm really going to do it since I've got issues with having
all that crap on my bike.  Besides, when we were kinda of lost in the
Pines Barrens in NJ on ToPA, one of the GPSs people had only showed a line
with another line crossing it which was no help whatsoever in figuring out
where we should go.  I just used my compass and said, hey, we're going due
east, we're in NJ, so eventually we'll hit the ocean and we can turn right
to get to Atlantic City.

Getting back to the point though, what would be a good one of these things
for a bike that isn't too big or heavy.  What tool would you call it that
would let me set up a ride and save it and edit while riding if I need to
change the route.  Something like how bikely works.  Can anyone out there
answer that question?  If so, can you explain it in a language I'll
understand and not be too technical.

Thanks.
Debbie
