Craigslist owns, used equipment stores are good too. If you find a nice guy who doesn't want his stuff anymore, you can probably get it quite cheap. If I were in your position, I would use the dumbells for harder crunches, id be doing pushups, slightly weighted squats, just about anything I could do with the dumbbell! Be glad you aren't useing a pillow case full of magazines and a backpack full of railroad ties like I was. :P
Small fridge and a surdy chair, desk, etc, and you can start dipping, just be careful, the fridge is probably going to wobble a bit.
Calisthetics, etc.

You can make it work if you try, just make sure its safe and sturdy before you start using it. I used an old rake/broom stick to practice squat form with, (Do not try to put the stick over your head with anything attached to it, very risky and damaging!!!), You can probably fill milk jugs with water and tie them to each end of the broom stick and curl it.
Might I also add that a Doorway chinup / pull up bar is only $14-$20 US dollars.
Crossfit and Rosstrainning are also good for low budget...
Another idea, cut down a tree, cut it into a few blocks, sand it down, throw a soft towel over it and you have a Flat bench, make a few angled blocks and you got decline. Probably won't work well, and you would need a solid tree...
