I bought the GOTY guide and really felt like I wasted my money. It actually just confused me more in most cases. My advice is to save your money and just visit uesp.net when you need a nudge in the right direction. It is much more helpful and most importantly its free.
I have a vanilla and a GOTY guide and do not see anything confusing about them. They are very well written and have excellent maps. They also have some background and comic relief in them. I have to admit I mostly use them for the maps now. I see no reason to fire up my computer and go to uesp.net just to look up a location. I like a hardcopy of the maps so I can look at them and be on my way. Just like any guide or website uesp.net has been know to have wrong information but I tend to trust my hardcopy guides more.
@ op you will have to go to Amazon or ebay to find one.
