I've seen & bought great ones in denim or some other heavy material super cheap at Target & Walmart. Also Hobby Lobby has great ones, my first bag was from there and I still use it.
You might just want to go with that since it's an emergency and keep an eye out for what you REALLY want later. It's also good to have those that you don't mind letting get all beat up if you travel or something.
I was glad I waited because the Jordana Paige one I fell in love with was too expensive for me, so I created an eBay alert for it and with patience got the EXACT bag I wanted for 1/2 the price, brand new! Someone bought it & never used it.
