...it's Colpitts, Hartley, Clapp,Butler and Pierce!
go with Butler since it has the crystal inserted between points of low
impedance, it actually boosts the Q of the crystal above the unloaded
Q. this Q is ths single most important source of jitter and attendant
phase noise.

Good grief I wrote that rather late at night.
Have you seen a simple Butler cct using JFETS? The ARRL one uses a
transformer which I rather not use.
