Hello - I'm new here, I hope I don't violate too many rules right away...

I have been reading through this thread that has been going for almost two years now. I still can't make up my mind whether to change my GPS receiver and would appreciate your help very much!

My N770 came with the Nokia LD-3W. There's many things I like a lot about it:

- uses the same charger as the N770
- is small and well designed, looks rugged, is most likely rainproof and the one button is quite safe from accidental push
- lasts a whole day, and often more, on battery

I am not impressed with the time that it takes to acquire position, especially when moving, i.e. on the train etc. Also it seems very good in the open field to maintain signal, but when in built-up areas it does drop off sometimes. Now from reading this thread I know not to expect instant acquisition, but again, I often find myself getting impatient with this one. And later in the year I am heading for Japan, a country that has given "built-up" a proper definition :-)

The LD-3W uses the SiRF Star III. Is that still the bees knees, or desperately old tat? Is it worth upgrading to a different receiver?
I like the data logging function of the i-Blue 747 as I don't always want to take the N770 with me when I go for a walk. But the design is not so amazing, especially the button. I could not find any reference to it's size anywhere - how does it compare in size to the LD-3W? How do the Holux receivers compare in size, and can they be charged with the Nokia charger?

Have I missed another worthy alternative? Or should I stick with the LD-3W?

Many thanks!
