Default Plexi, Lexan or ???

Hi.

I am building an amp and will be using a clear plastic over the front panel
graphics.

I could use some help in choosing the material, such as Plexi or Lexan.
Since I will be drilling couple of 2" holes to mount panel meters, I need
some suggestions for which material is the best to work with. A hole saw in
Plexi is prone to crack and maybe there is a better choice. There also may
be a better method for creating the holes than a standard hole saw.
Suggestions???

1. If you decide to use the plastic water with a bit of detergent
makes a good coolant/lubricant. Keep the cut flooded.

2. I made a lot of panel covers inthe past by laying out the panel in
Autocad then flipping the drawing layer with the graphics on it to get
a reverse image. I then made an overhead transparency of the graphics
and used the transparency over the metal panel. The result was a clear
plastic cover with the printing sandwiched against the metal panel.
It worked quite nicely. You might want to consider it.
