Sarrod, the price definitely is a large pill to swallow but once you can get over that or a convenient "oh not much more than my PaperWhite dear" then it's a lot easier to swallow.
I know some have had concerns about the leather case not fully encasing the rear of the Kindle allowing for possible marks/scratches. So far I haven't seen any evidence of that but it's possible though it may happen. However I think with the case being leather, I think the leather will probably degrade/mark more quicker than marks on the back of the Kindle. Amazon have some third party cases already that let you fully cover the Oasis however they don't permit for the battery case being on the Oasis. For me I'm using an Amazon Zip sleeve for transporting mine around so it doesn't get scratched up, it's just a fabric book sleeve mostly used for 7" Kindle Fire's but it's got protection and padded and has a zip so it won't fall out.
The Oasis definitely is worth the extra money, it's just getting over that first hurdle
