BigIron,
If you have a decent UPS Store around Wichita, try them for a nice 100% (and accurate 100% it is around here!) copy or several, before you laminate the plans. Out here that's $2 per.
Laminating may degrade the copy suitability. Getting the UPS Store copies gives you a master for the hordes of people who will pester you for further copies, a working copy, a copy to chop up for templates, and some more paper to crowd your plans storage barn.
