Unlike software dedicated to limited tasks, an individual crystallographica implementation will grow by the accumulation of the user's own scripts, and thus become yet more powerful. An analogous process at the developers' end should lead rapidly to a solution of the anomalous dispersion problem mentioned above. Value for money. I think it's over-priced though I know of no other similar product with which to compare it. However it's no more than the cost of an electronic module that might form a very small part of the experimental apparatus that produces the results that crystallographica is called upon to analyse.
