Also check out shopgoodwill.com for prices and machines. I got two FW from them and one I was able to pick up locally saving the shipping charge the other was very well packed.
Don't forget estate sales - sometimes those are listed there too. You can get good deals. It appears you are in a big city and those machines tend to be more expensive. Are you willing to drive a bit? Just figure out what you can spend and stick to it.
