Thank you to everyone who provided information.
Based on descriptions of the different tools, some are wimps and some are tough. A lot are rated for the size (up to 3/8 inch) and material (steel or aluminum) of the nuts they can set.
The most common higher quality tools are Marson and kits are sold for between $60 and $120 depending on the seller and the mandrels that come with the kit. Each thread requires a corresponding mandrel, and buying more is around $15 each.
Then it gets confusing because some of the Marson tools are described as up to 1/4 inch, and others that look the same are up to 5/16 inch. It's not clear what the difference is. McMaster Carr has a large selection, many looking like the Marson tool, but at a wide range of prices and ratings.
I am assuming that you can use any nut with any tool that has a mandrel with the correct thread. There seem to be a range of nuts (see McMaster Carr), so it may be worth looking if you have a special application.
