$10-$20 is a fair price of a front surface mirror. Why does it have to be front surface?
Because a rear surface mirror requires the laser to pass through the glass surface twice,
use old hard drive platters

Mylar is attractive because of the price, so if I can get that to work, hell yes. I guess I was put off by mylar because of the mylar tape I bought which has an unwanted texture to it, but this stuff I found on eBay seems very smooth.http://www.ebay.com/itm/MYLAR-GROW-ROOM-LINER-Hydroponic-Reflective-Mirror-Film-Shiny-B-W-Poly-/120926245135?pt=LH_DefaultDomain_0&var=&hash=item1c27c4110fThink that would work?
