If you are diligent enough you can get one for under $100 and in good condition. Just make sure you hit all of the estate sales you can and check CL in your area and you will score one.
I missed one about 3 months ago for $65 and another on for $45 about the same time. One was on CL and the other was at an estate sale. I saw the $45 one at the estate sale ans missed it by 20 minutes. I recognized the case when we we in line checking out and was floored when I saw what was written on the sales slip.
