Safety Speed Panel Saw (H4, H5, or H6). An H5 will cut 5' tall panels vertically or can be turned to rip them, and is a good choice. Cons, makes dust. Pros included an option to hook up a vacuum to minimize dust and the ability to cut nice square panels. Different blades may be worthwhile if you cut a mix of materials (acrylic needs a special blade, but ACM and MDO wood can use the same blade). Try not to drop material on the plastic rollers - the are replaceable but you will need to adjust them so they line up properly with the others (to keep your material level).
