I agree.

Oh....I was under the impression you needed something like less-than 
50 HERTZ stability. My bad. :-)

In the interests of simplicity, low cost, and least effort, I would 
use a Heathkit LMO, a 6BE6 oscillator/mixer with a 3.5 Mhz crystal, 
and a very simple power supply, and mount everything in or on a 
minibox.

I would keep the B+ voltages low.

I can send you a suggested schematic for such if you would like.

You would use slug-tuned coils and fixed capacitors for the 
mixer/oscillator.

Total cost, not including your time, should be under $50.00, IMHO.
