Well, I'm an Independent Claims Adjuster down in Puerto Rico. For estimating, I've got the National Estimator (Craftsman Books) whose prices I've adapted to Puerto Rico's prices as per my experience.
As for mobility, I've got a LapTop with a small printer and a small scanner (they all fit in the laptop bag) and a car desk with power inverter, so I'm able to settle claims on the spot.
I keep track of time and billing with "Time Logger", which has been great for the last few years.
Did not know about Symbility, and it looks very interesting, so I'm gonna look into it.
