Thing is, a book, like anything else, is only really WORTH what someone else will pay for it. They can ask $1700.00 but that doesn't mean they'll actually GET that much (unless someone with more money than sense comes along and just has to have it.)
Me, I wouldn't pay more than 30 bucks (even if it was in like-new condition) I can often find many of the same forms found in a Google or Bing image search , and if you can get at least one known dimension, then using a bit of math (simple matter of scaling) easy enough to figure out the remaining dimensions... So yeah, I have a couple copies of some of the other books mentioned, (highest I paid for one was $23) and once seeing the "nitty gritty" of how the books are put together, it's easy enough to just save images of different forms that catch my interest - most can relatively easily be duplicated (or close enough) and others you can often infer a lot of the dimensions based an arbitrary value (assign some point a value of X and then just use that same scale to get remaining measurements)
