I'm usually on with my permanent account, so I hadn't seen them, but yikes, yeah, sounds like sticking with Google is the best bet.
Some ideas if additional funding is needed:
First, maybe some Tweak-themed items via CafePress? That could get money up-front from us buying things like T-shirts and buttons, and stuff, and then it would also let us advertise you to the world.
Also, for my smallish fansites, I always had really phenomenal luck with the Amazon.com associates program. Their banners and buttons and links tend to be very unobtrusive and non-intrusive, and generally give great commission returns.
I will definitely make another account paid as soon as I can afford to, though. Thank you for watching out for us.
