I have copies of both the limited edition and the regular. I would suggest NOT ordering it on Amazon, because no matter how sturdy it is, it will arrive beat in some way.
Both seemed sturdy enough to me, but the plus for the limited is that it has two place markers and the book doesn’t slide in your hand while you’re reading it. With so much information to absorb, I actually found it worth the extra money.
I'll second this, at least for the standard edition. I went through three copies, and decided to keep the least damaged one as opposed to ordering yet another damaged copy, since the price was right for me. I dread to see what condition the limited would've come in. For the record, it looks like short of boxing the book, it's just too heavy for Amazon's standard packaging, and at best you'll get a dinged corner.
