I currently have a Bodnar dual frequency unit, that gives me frequency and a TAPR, (Synergy Systems) that gives me 1 pps, but I would like something that gives me both, with better performance (holdover).

….. holdover? 

What are your holdover requirements and what drives them? That is likely to have a 
significant impact on “what makes sense”. Holdover on most GPSDO’s is driven by
a network timing requirement ( X us over Y hours ….). Most basement lab needs are
not driven in the same fashion.

I’m sure a call to Jackson Labs will get you the current price on any of their products.
