I have several house rules in place for wizards that you might want to consider using.
First, my game world is very low in magic, so no magic shops.
Also, I dropped the 'automatic' spells the wizard gets at each level.
Before I get flamed, the wizard gets some things in return.
Some of these are not the topic of discussion here and so I will not name them.
What I did do was drop the cost of copying from a scroll or existing spell book, although they still need to make spellcraft checks. (So, in effect, all spells are 'free', but they need to find and learn them first).
I also reduced the cost of creating 'new' spells (which is the way you can get existing spells you didn't find) from 1000 gp per spell level to 100 gp per spell level. It still costs 1 week per spell level to research them.
This also allows me to keep tabs on the spells the wizards have access too, and if they inform me they want to research a spell I can inform them the research fails when it is a spell I don't want in my campaign.
When I'm feeling generous, I/you can inform them of this before the research time and money has been spent.
There's also the option of granting a similar, but different spell than intended as a result of the research. (A polymorph subschool spell instead of the polymorph they were researching, for instance)
Hope this gives you some ideas.
