I am definitely not a big fan of kickstarter-advertised products. I'd rather an author wrote his or her product, play-tested it, found a publisher, and made it available to us in dead tree format through our Favourite Local Gaming Shop.
However, I also know that 99% of rpg authors have a day job, and the 'normal' procedure above may not always work out for them. Thus, in spite of being fully aware of the harsh realities in the life of a non-professional rpg author (hey, I am one of them, after all), I still do avoid kickstarters because they're usually not delivered on time — If and when they are delivered: most of them seem not to be, if one is to believe all the stories that get mentioned here and there.
This having been said, I sprang to my credit card when I saw the kickstarter for Collectanea Creaturae by Travis Casey and Julian Stanley. Travis and Julian have consistently been posting excellent stuff over at the Monsters & Magic community on Google+ (I love their Alchemist sub-class), so a book of monsters for M&M by them was a no-brainer.
At the moment, the kickstarter is fully funded by the current level of pledges. However you may want to jump on the bandwagon, especially if you live across the pond— the $25 level of pledge gets you a dead tree version of the book rather than the PDF. Unfortunately I did not choose that particular level because of the extra cost of shipping to Europe ($20). Sigh.
