I usually use the 2×4 under the plywood approach. For crosscutting, I use a 50” straightedge clamp and a circular saw with a cutting plywood blade. For rip cuts, I have an 8 foot striaghtedge clamp which I want to replace. I am considering the Kreg® Rip-Cut Circular Saw Guide KMA 2675 (available from Rockler stock #47494). It retails for about $35 and will rip from 1/8” to 24”.
