I did it for $25... $7 for the GPS+antenna module, $3 for an Arduino chip on a PCB with proto area from China (should have bought a lot more when they were available), $10 for a small ovenized 5V TTL output OCXO (also should have bought a lot more), and $5 for misc parts (OK, beer money not included in the BOM). Batteries not needed, powered off USB. It worked better than I expected... not Tbolt quality, but not too shabby for a thee-day weekend hack. $50 (and a lot of work) is certainly doable for a decent home-brew GPSDO.
> 50$ for a complete GPSDO, batteries included, is quite a low price limit.
