I find that test strip sgive you most of the information you need with the first try. I use a strip about 2 inches wide placed along an important area of the image and use the same 2,4,6,8,10 sec exposure. I have found that gives me enough to make another strip that will allow a good guess at what to print the test print at. A test strip is much less expensive than an analyser and it allows you to see what the densities look like. If you have to be concerned with the cost of paper, then you need to find something else to do. Photography has certain basic costs and if these are too high, then maybe you should take up knitting.
