HELP! Laptop (or desktop) needed.

Recently my desktop crashed beyond repair. Then my laptop crashed. Then my netbook. I'm hoping to find a great deal Black Friday, but I really could use one now, if anyone has something they could donate, it doesn't matter if it's old/ slow.

I lead a free writing workshop for women in Crown Heights, and I've been using the computer lab at school but it would be nice to have one at home.

PS, willing to babysit/ walk dogs in trade! Thank you!!
