I suppose you noticed that the seller's location is Singapore. I would be
wary of an unknown manufacturer from outside the U.S., particularly in the
areas of a concise operating manual and product support.
There have been some complete new systems listed on eBay recently, made by
reputable manufacturers with U.S. distributors which can provide product
happy with it. It has no calculator or bolt circle functions but works
very well and has the 1/2 function and Metric/Inch etc.
The best part about it is it comes from Ken :) Wonderful support and about
half the price. It does not use the glass encoders but I understand it is
possible to use them if you prefer. Personally I like my handheld
calculator better than having one hangining on a bracket. I am not sure
what the big deal about a bolt circle function is anyway. Not a problem to
figure out for the few times you are likely to use it.
