Info on Coax Connectors
I've converted to using crimp-style coax connectors rather than solder type -- they're much easier to work with (if you have the right tools!) and the research I've done indicates that they're every bit as reliable as a soldered connector.
I highly recommend Davis RF as a supplier of coax, connectors and accessories. This table provides trimming information for the connectors I use most often.
