BNCconnectors

[pamphonica]

I have had good success, right up into multiple GHz with crimped BNC connectors. If you get the right ones, both the centre pin and the screen are crimped, and the the tool costs £20 or so. I have put crimp BNCs onto RG58, RG174 and RG316.
This tool should have the relevant set of holes for pins and braids:

But check the data sheet for the crimps you want to use to find the exact diameters you need. RS components are a good source.
I do also use pin-soldered BNC plugs but make sure that I use the minimum possible amount of solder so the pin still fits.
