Welcome to the PME brotherhood! I think I may have been the first PME owner in Oz and had to thrash out the SH problems with the Bisques... happily long since resolved.
and am happy to say it has delivered years of trouble free and dead-nuts-accurate performance.
The one thing which will help your modeling and subsequent pointing accuracy is an accurate time base. There various ways of doing this, but I've found
NMEA time to be the best. One second of time means 15 arc seconds of error...GPS time is within a few milliseconds of UTC with a cheap GPS effectively giving you atomic clock accuracy.
A 30-50 T-Point model is more than adequate. I found using a planetary web-cam and cross hair on my PC screen gave consistent modeling data (..err don't use a permanent marker
)
I'm sure you'll enjoy the new addition!
