I happen to have a two bedroom apartment in Elkins Park, reasonably priced and well located.
That's a touchy question to be asking licensed agents. It could lead an agent into steering you (per the Fair Housing Act) towards certain parts of West Mt Airy.
I would say your best bet would be to find an agent you like, request some current rental listings from him/her (based on your criteria), and go out and see different parts of the neighborhood in person. That will be the best way to get the answer to your question.
Please let me know what I can do to help you out.
