Need new insulin pump

Hello. I've recently lost my health insurance. What better time to need a new insulin pump? My pump is out of warranty, and Animus said that they would replace it, but it is going to cost me around $1,200; however, if I send them my current pump, they will deduct $500 off of the total. With my current living situation, I cannot afford to pay out the $700 for the insulin pump. I desperately need a new one. Any help would be greatly appreciated.
