ASSUMING (which no published setting does by default - even Forgotten Realms) that you have access to Ye Olde Magicke Marte with any spell in any book available for purchase as a scroll, a 3rd level spell costs minimum 375gp to purchase, and then 300 gp to scribe. A level 5 spell costs a minimum 1125gp to purchase, and then 500gp to scribe.
Everyone seems to assume the wizard is getting all these spells free, usually by trading with some conveniently available other wizard. Except the ability to find such a wizard is contingent on the DM, and is in most cases less available than the scrolls that show up as random loot on encounters.
Someone in this thread even went so far as to say it is the DM's job to make these wizard spellbooks available to the party wizard. No, it is not. In fact it is the DM's job to prevent such a thing from happening too often. Under no circumstances should the DM be proactively taking actions that make the strongest class in the game even stronger.
