Apropos Wenzel: Is there any distributor that sells them in
single quantities? Or do i have to get them from Wenzel directly?
And is there any price list available?

Why an OXCO? AFAIK the temperature has only an effect on long term
stability/drift, but doesn't affect short term effects (which cause
the jitters). Or am i missing something?
