236, I think. http://holux.com/ has instructions for battery changing on this
unit. But any of them will probably work and the idea of a spare battery is
more a belts-and-suspenders kind of thing as they all probably come with 12vdc
adapters as well.

I checked online, and found the newer Holux GPSlim236, but it said
nothing about cell phone battary. Are you thinking of the OnCourse SiRF
Star III? $110 new!

I have a bluetooth Holux 230, using it with ChartCase. Ebay for about
$80. Works well and battery life is more than 6 hours. 2 x 3 hour
flights. It may last longer than that.

That being said, I would buy their other model (don't remember the
number) that uses cell phone batteries because then I could carry a
charged spare.

When I bought, I thought an external antenna would be important. I
have tried the Holux with its internal antenna, with an external
Garmin antenna mounted on top of the airplane, and with my Garmin 195
suction cup antenna. No difference in sensitivity. I mount the Holux
to the windshield on a little home-made suction cup bracket and use
the internal antenna.

I saw no reason to pay up for the Garmin name and still do not. I
compared this unit to my Garmin 195 (before I sold it) and saw no
difference in terms of sensitivity.

Hello!

The new version 3.0 of Seattle Avionics's Voyager just came out, and
it has a nice moving map. I want to start using it on my laptop, but
need to buy a GPS, first. SA recommends the Pharos GPS360, but I
always thought the Garmin GPS 10 may be the better option. Does
anyone have experience with any of these?
