You can aquire inexpensive front surface mirrors of a decent quality from companies that sell stained glass supplies. I purchased some that were approx. 8" x 10" for $17.
By the way, the main benefit is that you will not have the second ghost image from the glass. Think of a rear view mirror in a car... If you flip it one way you see the reflection in the mirror which is brighter than the (in the flipped mode) reflection in the glass. The rearview mirror is actually a prism where the front surface of the glass and the mirror surface are a few degrees from parallel. When you bouce a projection off a traditional mirror you get a second ghosted reflection from the glass..
