I personally have met the Shooting Star folks and their units would
likely work for you. That having been said, I recommend the basic
Mitutoyo setup. It isn't that much more, and it is a much more
robust, pro unit.

Calculating bolt hole centers, whether in a circular pattern,
elliptical pattern, rectangular array or whatever is a simple
problem if you have good math skills or are good with a spreadsheet.
If you aren't, and if you think you might need bolt hole software,
then look for it. Me, I wouldn't pay five bucks for that feature.
My DRO has it and it's less hassle to figure them out on a
spreadsheet than to go find the manual and make the DRO figure
them for me.

Soon going to add a DRO to my 10x50 mill... looking at the Shooting Star
kit, 3 axis for under 800 dollars. They have been very quick and
helpful in
my inquiries so far...

Anyone have constructive opinions regarding my upcoming purchase?

I was wondering how important the "bolt circle calculation" is on DROs,
as
the Shooting star unit does not offer this feature. Obviously it is
correlated to how often you are going to be doing this, which for me
would
be seldom... but I was just wondering.


Thanks in advance,
