I don't think we can answer that for you.
What do you consider to be fun? How much money do you want to spend?

There isn't much point in talking nanoseconds if you are going to connect it
up to a computer, especially one running a normal OS. Things get more
interesting if the system has special hardware.

I'll split the market into 3 chunks:
consumer gear, high volume low cost
telcom: medium volume
lab: low volume, expensive
If you want to get started, I'd suggest the GPS-18x and playing with ntpd.
