What's the value of a spellbook compared to the value of a scroll? Because scrolls do more than give you a spell to put into your book; they give you a means to cast spells beyond your current slots (in numbers and levels.) Your assessment of the cost is off.
It isn't, technically, since you would have to buy that scroll to scribe it into your spellbook, or find some other way of learning the spell, which usually entails some kind of a cost. But since they're only scribable, we could say they're half as valuable. Which still leaves over 33,000gp. That's close to the price of a +6 stat enhancer, and a bit over the price of a +3 weapon. And it still isn't taking into account any costs for scribing spells into your spellbook (100gp per spell level, which would be 4,100gp if you took all the bonus spells as 1st level spells and didn't have a Boccob's Blessed Book). If you're like that guy who mostly plays wizards in our group and intend to know all the spells from the PHB plus assorted spells from other source books, you're saving a big darn pile of gold with this feat.
Besides, nothing says that a Wizard can't choose learn the same spell multiple times if they wanted to for some wierd reason. Tadah! Instant free duplicate spellbook that you can give to somebody for safe keeping while you're off adventuring with your original spellbook. Or if you normally keep an 'adventuring spellbook', you now have two copies of your spellbook to be stored in two different safe places, for the cost of a feat. And if you're an item crafter, you're just going to love being able to pick those 'only need the spell for this one item' spells for free instead paying gp for it.
People also always raise the point that there isn't unlimited time for item crafting when the balance between sorcerers and wizards is debated. Well, this feat just bought you 41 days for item crafting, with a wider array of possible items to boot.
Still, the feat isn't too much out of the whack in general feat balance since it must be taken at 1st level, when most characters can only take one feat (when the feat, by the way, technically doubles the wizard's wealth). But it is still a powerfull feat.

The sorceror risks nothing with his choices: the mage could loose everything.
So if I made a feat that gave sorcerers a spell book with the normal wizard progression, but they still needed to memorize spells each day the same amount they would normally know, it would be balanced since they could lose everything too?
How often in a standard campaign does a wizard loose their spellbook? I bet about as often as the paladin's Holy Avenger gets sundered. That is, very rarely.
