10MHz reference-frequency clock

Anyone know of a clock driven off a reference frequency of 10MHz? Seems all the designs I can find online are of most nominal frequencies BUT 10MHz.

Considering how cheaply they can be purchased now, as well as other interests of mine (which I'll keep secret for now ) I'm planning on building a rubidium 10MHz reference standard for calibrating my ham radio designs & other projects.

Now, that doesn't have much wow factor sitting on the bench by itself, so I wanted to integrate a clock into it that would stay true to its level of accuracy (+/- >10e-11/yr drift). That would not only give me what I need it for, but something that could also from time to time, serve as a conversation piece - not to mention, give me another project with which to fill my never-ending desire to build and construct.

I've tried googling this, but 10MHz reference clock pretty much brings me to DIY frequency standards or Agilent counters that I'd need a car loan to purchase.

Thanks.
