Are there any prospects of salary adjustment after you move up to managerial grade? Or, do you intend to jump ship and go work at a different company at a managerial level? If your answer is yes on either of these questions, you should definitely take up the managerial title. Even if you haven't thought about those, you could think about those possible routes now and see if that career path is what you want to pursue.
Since you are at a non-profit agency, your prospects of getting a higher salary is pretty low. If you have career ambitions, you'd really have to go elsewhere. In the US, especially, there is really no need for regular employees to feel any loyalty to the companies they work for. They are buying your talents to perform their business operations. It's a business exchange that doesn't really need any emotional attachments. Things might be a little different in a non-profit organization, and you'd have to consider how much you value the altruistic contributions your job gives you. But hey, if you end up getting a higher paid job, you could easily contribute those extra $$ back to whatever good causes you prefer.
On the other hand, if you are comfortable at where you are, and the lifestyle that your current job affords you, then sticking with the same title while collecting OT pay is the way to go.
