I don't think $33 for 600 pages is bad at all. Six cents a page. That's cheaper than mine, but we think in terms of "a product" rather than how many hours it'll give ya.
There aren't many comparables: TV/film histories/backstories that large (i.e. hours of reading) with so much exclusive content. If you want a book to sell in bookstores, it needs to be in line with the market. But this one is pretty unique. And if their model is as I think, they're trying to make up for smaller sales (not in stores, niche market) in larger profit margin. That can be a trap since people (as on this bbs) have price points in their heads based on the market and traditionally published books.
If I were that interested in that level of detail, I might bite, since you're getting a lot of book. Oddly, though TOS is "it" for me, I just don't care in that detail. Again best wishes to everyone and a sweet 2014. I am pumped for an even-numbered, solid-feeling year.
