@Mannyrock posted:P.S. Guys: Some Home Depots still carry 5/8 inch B/C grade plywood, especially in the expensive exterior grade (green stripes on the butt end).
I love 3/4 inch plywood, but the weight per sheet is troublesome when it comes to loading it in the truck and carrying it down to the basement.
I laugh when people claim that paying $50+ a sheet for quality plywood is too expensive, and then they run out and pay that much for a single boxcar.

3/4" plywood sheets seem to get heavier each year.
I agree with your boxcar comment. Remember that purchasing materials for benchwork is a one-time cost. If you build it right, you'll soon forget about what you spent. A lot of the materials can be salvaged and reused on your next layout.
But don't overbuild - good enough is good enough.
