Harold, Thanks for the reply. Where do you get the Murata resonators? My specific need (which I should have mentioned at the first) is for a 4 mHz ceramic resonator with caps built in. I am cloning a project that was prototyped with a Picstic and want to change nothing in the software. I don't ask these questions lightly. I've spent hours feeling stupid and frustrated on the web and on the phone etc and still don't know (but am learning more now thanks to this great list - though conflicting info still happens).
