Just to take up the point Isthmus made earlier - I do tend to warn people about computer readings simply because they do not synthesise - they simply give you a list of 'features'.
That being said, if you use the raw material and start to do your own integration you will find the material valuable. It's not so much a matter of taking the stuff with a pinch of salt as recognising that the process is not finished and needs some care and consideration to turn in into a 'reading'. Providing you do that Astro Com and others can be very useful.
