One option is Ramat Bet Shemesh. It might also be quite expensive by now, but the newer projects might be in your ballpark. It is very diverse and has TONS of English-speaking people. There is also an English-speaking community in Moshav Matityahu.
There are also more "Modern Orthodox" English-speaking communities in Efrat, Maale Adumim, and to a lesser extent Mitzpeh Yericho. If I am not mistaken, there is also newer areas of Safed being built and many English-speaking people are moving there.
Maale Amos and Meitzad are smaller settlements which are also largely English-speaking and are "open minded" Chareidi types.
I recently moved to Beitar Illit because living in Ramat Eshkol (a neighborhood in Jerusalem) was too expensive. Beitar is more "chilled out" than Kiryat Sefer but it is still heavily Hareidi and probably is mostly a kollel-type community even though there are a lot of people there who do work. Also, Beitar Illit is a largely Hassidic town. There are a significant number of Americans in both sections of Beitar Illit (A and B), there are no official English-speaking Shuls there, but there is at least one Shul in B which has a large percentage of English-speakers as well as other shuls there with a smaller percentage of English speakers. I'm not sure what the situation in A is but I do understand that there are more English speaking people in A than B. There is an English-speaking Kollel community starting in Karmiel, but again I don't that's what you are looking for.
This is all in addition to the options mentioned above by the other posters.
