Hi Alan,

I assume you are talking about the Z3801A's that were floating around a 
number of years ago?? They were a good deal when they first came out and are 
still available, but at much higher price. I was fortunate to pick one up 
early on. It's been running in the shack for over 3 years now as a reference 
for my test bench (counter, weak signal sources etc) and it drives my 
DSP-10.

What is your goal for stability? and what are you willing to pay?

You might look here:

With stability within a few Hz/GHz it might do the trick? A lot of us 
Microwave guys are using these.
