Hi,

I got one of these, which will let you do eight at a time and is under $150:

Give yourself some extra time to charge it once it arrives, since it doesn't use regular batteries.

I have a slightly more expensive Kolsol device: As well as doing the cable continuity it has a built-in MAC and will do basic link and IP tests as well as validate POE. It costs about as much as a Klein Scout Pro 3 but does way more, however it's not built quite as robustly as the Klein.

Whatever you do, avoid the cheapie ones - they're the pits...
