$50 in scrap yard (so called junk yard). $50 for installation. If you have place (seems you have), you can find a guy here to install for you. Very simple job.
Or go to a Chinese garage ask them to find used one and install for you. Please don't go "路坚". Seams lot of people are complaining it.
Or read you insurance policy carefully and see if you ever bought a "deduction" option. If the glass is very expensive and you have this option, you may use it.
scrap yard is the place people disassemble the old cars/accidend cars and sell for parts. You can check the yellow page, in automobile section; Looking for the ads like: Auto Pieces Usage, then call them.
