We used the Scripture ranges provided to us (with some modification), created e-texts for the facsimile introductions, and then interleaved the high-resolution images taken by the CSNTM. The end result is the first of its kind: a fully indexed, locally stored collection of high-resolution images of four facsimiles (including one pseudo-facsimile), and one original manuscript of the Greek New Testament.
The module costs $179.00 and includes images of the following codex facsimiles: Alexandrinus, Sinaiticus, Vaticanus (pseudo-facsimile), Washingtonensis, and the original Codex 2882. These are also freely available at the Center for the Study of New Testament Manuscripts (CSNTM).
I think it is nice with all sorts of resources in textual criticism, but of course images of the real MSS are preferable to facimiles (e.g., Codex Sinaiticus). Nevertheless, we get here a convenient way of looking instantly at the manuscript evidence in connection with the study of a certain text in the Greek New Testament.
Update: Pete points out in a comment that the module includes links to the online images of Codex Sinaiticus
