Thanks, Monty and Sean,

I will try out the Royaltek. You indicate "2xxx" as the identification of
the device. I have seen some discussion of the rbt2110 which seems to give
17 hours of battery life which is certainly very attractive. Are there other
Royaltek units that people are using? 

All the best,

Hello Cearbhall,

In my opinion and everyone seams to have their own, I would say that the
Royaltek 2XXX and the Holux M1000 seam to be the all around best.

Other receivers with non-SiRF chipsets have impressive specifications upon
first glance but in  practice they often fall down in areas relating to slow
speed.

What do others have to say on this topic?

Best regards,
   Monty
