I guess the first question would be - If you have a Time Pod, what do you need a counter for?

Based on a guess that you need extended frequency range, either would do pretty well. My vote
would go to the HP for a couple of reasons:

1) It’s more broadly supported in terms of driver software (which may or may not matter to you).

2) It’s a more common item on the auction sites, so parts are easier to find.

3) It shares some parts (like the power supply) with the (cheaper) 53181

No those are not great big reasons to go for one over the other. They are very similar devices. One
has an LCD that has a finite life. The other has a VFD that also has a finite life. Both are custom, that’s 
a tie. Some like the command (button) arrangement on one over the other. I think it’s more a “what
are you used to” thing than anything else. On the 53131 you need to hit the Run button in some cases. 

I have not watched the prices on the Fluke. I have kept track of the 53131’s. A “good price” on one
these days is below $600 ( = you may need to shop a bit, but they do show up).
