(To fellow newbies: While the translators use the term ‘I Ching’ in translating ‘易’ (Yi) of book titles, the books are not about the Yi Jing. Re: (1), the translator (Xuan Wanyan) uses a 1770AD version of Zengshan Buyi.)
It seems only (1) is currently available (from Amazon, et al). (1) comes in two books -- Parts 1 and 2, with each part covering two volumes of Zengshan Buyi. The total cost is about US$300 equivalent (depending on site and country of purchase). Sadly, yes, it is expensive compared to regular e-books
