Although I totally give thumbs up for soldering method for obvious reasons, I would not depreciate epoxy thing. There are many epoxy types around, some of them producing heavy, metallic/rockish thing, that even produce semi-metallic sound, when hit I would say that those types are less elastic that solder, really! I think it's going to break like stone, instead of changing shape, even for a while.

Still, IMO soldering is much better - because soldering characteristic, including shallow diffusion - and I'm going to do it. Probably, after good soldering, I'll also "encapsulate" it (in sane manner, of course) in good'old'epoxy. Which I think of as gaining best from both methods, unless someone prove that I'm wrong.

BTW, I totally agree that "modding" cover to fit soldered port is eas and doesn't involve any complicated tools. Can be done with sandpaper, if with nothing else.
