I don't recall if Linda has the single or double saw setup, but I bought a Phaedra about 14 years ago and am still using it with no hitches whatsoever. It is a simple, very accurate, calibrated table system that has no moving parts to speak of to wear out and, if you are a small shop or just going into business and unsure of how fancy a saw to buy, this is the perfect ticket. There are dedicated saws on the market that are excellant but much more expensive.
If your sawing requirements are such that you can get by with 2 good commercial chop saws and a calibrated table, I would highly recommend the Phaedra system. The only reason that I would sell mine and get a CTD or another dedicated saw would be to handle a large increase in business in my new location. Otherwise, I am sticking with my Phaedra.
