Has anyone had any experience with Martin Johnson Mfg.? Model Railroad Accessories | Model Railroad Tables | Model Railroad Portable Tables | Model Railroad Hobbyists | Railroads Their website advertises Modular Model Train Tables - 2' x 4' domino style bench work that can be set up, locked together in just minutes and without tools. The top is ½" fiber board supported by a custom extruded aluminum frame. The adjustable legs are made from welded 1-1/8" steel tubing. The legs are adjustable from 20" to 42". The 2 ft x 4 ft dominoes modules fold to a 2" thickness for storage. Domino Benchwork with standard ½" fiberboard top is $74.50 Sievers pre-fab benchwork is close to $100 for a 2' x 4' with fixed-length legs, and Mianne is over $120. I have an 8' x 10' corner space where I could put a switching layout that might eventually be expanded in another location, so four portable 2'x4' modules would work well. If you've had any experience with this manufacturer's products, or even any anecdotal information, or even thoughts and impressions, I'd really appreciate your sharing. Thanks!
