I see on internet handhelds also by Franklin, Royal, Seiko and Lingo.

Any info on these brands?

Big concern is, as always, do these have ac adaptors and are they universal re accepting 120 and 240 volts?

Ectaco ER 200 DM can be had for $84.95 on Amazon, but apparently it has no ac ability.  How can batteries be recharged.

Ectaco ER 400 can be had for $199 on Amazon.  It mentions ac adaptor, but doesn't tell if it will take both 120 and 240 volts.

Anyone have experience here?

Thanks
