ROM preservation

I've been thinking recently that I should possibly get a ROM reader/writer so that I can preserve the ROMs out of all my old parts, and I was wondering whether anyone had some experiences (good or bad) with any different programmers? Which programmers are good, which aren't so good, and why? Where is the best place to get one, and which is the best to get on a tight budget? What about making your own? (Note that I think this may be an interesting project, but I'd really rather put my time into other things right now, so this is near the bottom on my list of options...) One called "Leaper 3" interests me because of its ability to copy one ROM to another without any kind of computer hookup, which I imagine might be useful, but I know nothing else about it.
