Lexan waterjet cuts really nicely.
Laser cutting it leaves a bit of discoloration on the edge, but isn't that bad.
The other option is to find someone with a CNC mill.
Given proper tooling, they can even cut your T-molding groove with a CNC.
For the stuff we do at work, it usually shakes out that CNC is cheaper than Waterjet, and Waterjet is cheaper than laser.
That may vary in your area depending on who needs business at the time, so I'd check around.
