Hey John

You've opened another can of worms with this one. There are so many different opinions and ideas out there that you won't believe it. Anywhere from a box-beam made out of plywood, to I beams, to square tubing and of course the ladder type which you mentioned. The ladder style has been used often and to be honest with you, I don't think any have been complained about. My belief is that you could use about anything, as long as you use enough support to keep it from sagging. I like the plywood box beam, with 3 or 4 supports. It's cheap, small, and with the proper support, will function very well, and not be a hindrance(?). You can build it on a table top, on freestanding posts, or even hang it from the ceiling. Lots to choose from. I think whatever fits in your shop area and makes you feel comfortable will work just fine. Just watch for square and straight. You've been there and done that, I know. Enjoy !!
