Computer Brain uses computer programs, which are digital records that can be easily copied and found on the Internet, so they are going to be cheaper (and that is just a suggested cost, I use a similar cost for Computer Brain in my games for legitimate programs). Basic (p. 71) says that the GM determines the cash cost of the materials for Super-Memorization, and my costs are comparable to the costs given for Grimoires from RPM, if you replace the cost per +1 for one ritual to cost per CP for a broader skill. Now, everyone will have their own costs, and $100 per CP may be suitable for some settings, though that would represent books you could get from a Barnes & Noble or that you could purchase on a Kindle in contemporary society.
