The author will present a practical reappraisal of available and "soon-to-be" available instruments and readers for photo-optical data reduction. Some aspects of the trade-off between cost and capability will be discussed in terms of a "building-block approach" whereby a modest but versatile system may be installed and expanded as needs require.
