Im using 75 micron self adhesive vinyl for the panels of my cab that don't have graphics on. I bought somewhere in the region of 10 square meters of matte black, royal blue and carbon fiber effect and it came to around £25 ($50ish). I bought way too much so I can experiment with a few things, you could get away with buying much less.
Obviously this type of vinyl wont be a hard wearing as laminate but it should do for my needs.
If you do use vinyl contact your local sign writers/sign writer suppliers and go have a look at there vinyl.
As laminate is thicker you could get away with not having a perfectly even surface. As sign vinyl is so thin you would have to make sure your surface is completely smooth otherwise it will easily show any defects.
