Wizard help

[TimeLordLaxx]

So I have a wizard build going Wizard5/Incantatrix4/Initiate of the sevenfold veil7.

This of course leaves me with four levels at the end that I'm not too sure what to do with, Archmage is never a bad thing, but I was wondering if there was anything better?
For spellcraft checks on the Incantatrix metamagic I'm trying to get as much as possible, at the moment I've gotten skill focus and Item Familiar for feats that help the ranks in it as well as synergy bonuses. The race is homebrew and it also gives me a spellcraft bonus, how much I'm not sure yet the DM is working on it.

Any suggestions for what I have? or Ideas on what would be a good way to up spellcraft checks?

You should consider going wizard 3/master specialist 3/Incantatrix4/Initiate of the sevenfold veil7.You lose the 5th level wizard feat but you gain skill focus (spellcraft) and greater spell focus ( abjuration ),plus a scaling bonus on dispel checks.

Items that provide a flat enhancement skill bonus cost x*x*100,where x=bonus.

Edit: also a ring of Divine Insight (CAdv) can give a +15 insight bonus on a single skill check,and i think it costs 7200g per daily charge.
