I feel for you, we have been in the same situation for over a year now. Pregnant wife 39yrs old first child and breast cancer. Baby is fine after two chemo rounds. Wife did 8 and is now in radiation therapy. It has been a tough experience emotionally and financially. We had to sell a lot of things and forego many others and bills keep coming in. Wish you the best of luck with your situation, there is light at the end of the tunnel, hang in there and never lose focus.
Considering these cameras are now more expensive I am sure you will get takers. Try also posting it on other services like eBay if it doesn't work out here.
