Martin,
I wouldn't think there would be any difference between all the Sirf Star 3
receivers. By default, these sirf star 3 receivers have WAAS disabled. Do
you know if the RoyalTech is enabled? Last one I tried a few months ago
was not. We had the Holux specially modified with WAAS enabled.
Also, the RoyalTech I tried did not have a physical on/off switch. It had
a button. Has this changed?

Star III Bluetooth GPS receiver is based on the same chipset as the
Holux <ww.holux.com.htm>ww.holux.com.tw slim 236 but with newer firmware.
It appears to be a little beauty in combination with the Trekker and also
Braillenote GPS. After extensive but unscientific tests on Friday I'm
glad to report similar performance to the above Holux receiver, a
favourite of mine since getting hold of one last summer. Maybe the
satellite acquisition time is even a little faster. Independent reviews
also tend to favour the Royaltek for accuracy over others in the same
class. I think that one pays a little precision price for the better
sensitivity over older generation chips with the relatively new
<http://www.sirf.com/products-ss3.html>SiRFstar III based receivers but
for my requirements the trade off is more than worth it.

It has an on off switch and can also use standard Nokia batteries, a good
job really as autonomy is poorer than similar specked systems. The
package we received didn't contain a case or manes charger, but this won't
be a problem for Trekker users as the critter fits on the charger shipped
with our system, and because the profile is the same you can use the
1000sT case. I guess the lack of a pluggin charger could be a problem for
some users. Maybe we received an incomplete package.
Note: I don't recommend the Holux Slim 236 with Trekker yet as we have
found some problems with the combination.
The Royaltek 2001 costs just under £80 when purchased online and it rocks!
