It cost 1 Credit for those 4 Valuations entries...that's pretty reasonable.
There is also a Will for Peter:
62 TAYLOR PETER 11/07/1906 GARDNER, ST MARTIN'S GATE, NUNGATE, HADDINGTON, D. 01/06/1906 AT HADDINGTON, INTESTATE. HADDINGTON SHERIFF COURT SC40/40/34
This above cost nothing to view the entry however, the original document will cost you 10 Credits.
I guess it depends on what you want, for me I am only interested in obtaining copies of original documents so I use SP.
To the best of my knowledge Scotland's People is not offered as a free service in any library.
