The TPS2014 is pricey but it is a real pleasure to use.  I haven't run
across anything as capable and convenient with isolated inputs and
four channels.  Running on batteries is also much more useful than I
expected it to be,

Any particular bandwidth requirement?  Storage or computer interface?
Analog?  Digital?  What's your price range?

If all you are looking for is isolation from ground, a TEK 7904 series using an 
isolation transformer might work if the size isn’t a problem.  TEK also makes a 
differential input plug IIRK.

I’ve bought several.  Usually about  $200 to $300 on epay.  Plug-in modules can 
be found dirt cheap if you lurk.  Even dead modules are good for hardware 
parts.  Contact me off list if you’d like more info.

Regards,

Perrier
