Thanks for the comments.
As for Taming of the Slough, I was limited to the top 25, and it just didn't make the cut as far as general interest goes. I had to leave out quite a few volumes from my shelves. I think I'm going to create a couple of other ones for cavern/cave, training, wrecks, sea life, literature, etc. I really like that list feature, as it lets you send your buddies all the info that the need to pick up copies of the books that you're recommending. Next, we'll have to see if we can do the same thing for DVDs.
And as for the DIR book, I don't know what was happening there. I think I bought mine at the little shop in High Springs for around $14 a couple of years ago. Maybe that's Halcyon pricing...
Interestingly, they also list that pricing for the Dive Into History books. Has anybody seen the street pricing on them? I think there's a set of three. I'm especially interested in the U-boat volume.
Hope somebody somewhere got underwater today. Here, the weather was pretty nasty.
