This sort of information is useful. Perhaps a Wiki is the best document,
where people can put comments like this. I don't have a Wiki set up myself,
but I'd guess the sort of information one would want would be:
Described what a TI counter is
No doubt with an emphasis on time nuts uses, but I don't see any need to
restrict it just to that. (I did consider using one of mine to record the
speed of the traffic near my house!)
* Understanding the specifications and their importance.
Lots of them.
* Items to be considered when purchasing new vs used.
* Description of model X
Include any options that are available for model X.
Also any known issues - e.g. for both the SR620 and 8970B, they do in my
experience run quite warm.
* Description of model Y
* Description of model Z
Table comparing specifications between all models
* Models worth considering if your budget is < $250
* Models worth considering if your budget is < $500
* Models worth considering if your budget is < $1000
* Models worth considering if your budget is < $2000
* Models worth considering if you budget is unlimited.
