Yeah it's best to talk to a scholar about this because while marrying a woman of the ppl of the Book is allowed, it isn't allowed for a muslim (man or woman) to marry someone who ascribes partners with Allah (mushrikeen/mushrikaat) & I don't know if that would mean u aren't allowed to marry a christian or jew who worships someone other than Allah?
I think it's best for you to marry a muslim woman even if she isn't goodlooking because in the long run it will be good for you and your children. You don't want your children to got to hell and it will be very difficult for you to keep the mother from raising them as christians if you marry a christian woman. Also you will have difficulty imposing other restrictions, like not watching bad tv programs; not listening to music; not having/bringing in male friends; not having mixed parties or parties with music, dancing, wine, etc. And if you end up getting divorced most likely she will get custody of the children so do you want to be crying about your kids going to hell simply because you wanted to enjoy this world for a bit? Also it may be that a christian woman may lower your faith of islam and you may end up doing haraam things (like music, wine, etc) while a good muslim woman may increase your eemaan so you may end up doing more good things like nawafil, itikaaf, taraweeh, etc. (There's a hadith about marrying a righteous wife, i think it says that a righteous wife is the best blessing of the world or something like that, not sure of the exact words of hadith.) Even the Quraan says that the righteous women will obey and guard the husband's honor & belongings.
...Therefore the righteous women are devoutly obedient (to Allah and to their husbands), and guard in the husband's absence what Allah orders them to guard (e.g. their chastity, their husband's property, etc.)... Chapter 4, verse 34
That is because she fears Allah. An unrighteous woman on the other hand doesn't fear Allah so will not care about the restrictions set by Allah so you can never be sure whether the christian woman is faithful to you or is she bringing some other man's children, spending your money on haraam things, etc. (Just my thoughts)
so i think it's best to get married to a good muslim woman or someone willing to convert (imo someone already interested in islam, not someone who only wants to convert for marriage because then you may not know whether the conversion was sincere or whether she will go back to her christian ways should there be a divorce). There are plenty of beautiful muslim women even from asia. nonmuslims (westerns) aren't the only ones who are beautiful, you know.
of course, Allah has made it halal tor men to marry women from the ppl of the book so if there aren't any muslim women in your area then it would be best to marry a women from ppl of the book, provided that she signs a prenuptual contract about islamic restrictions, what religion to raise the children on, who gets custody of chidren, etc.
