I have a few RRS plates, and they are very nicely made, but I have at least a dozen inexpensive generic plates that I got from a guy who sells as "fletcher28wu" on eBay, and they work fine for most things. If you're just setting up and want several plates, as I recall, he used to offer discounts in quantity (like buy 5 or 6 and get one free). The longer ones have stops, and they seem to be compatible with all A-S style QR clamps including lever-lock clamps. They don't have anti-twist ridges, and aren't engineered to be as light as possible like the RRS plates, but they do the job. I used one of the shortest 1.5" generic plates on my Gowland, and would use the same one on any of the cameras you mention, or possibly the next size up for the TLR.
If you want to go with RRS plates, just measure and look for something compatible with a similar type of camera, or call them if you want more advice. They aren't in general customized so precisely that they only work with one camera or only the ones listed.
