Voltage Converter

All,

I need a recommendation for a robust voltage converter. It needs to
convert from 220V/50Hz to 120V, at maybe 200 watts or so. My problem
is that I will use it in the Republic of Georgia in regions where power
is not very stable.

The convert needs to withstand power line disturbances without damge.
Also, I would like to hear from people with personal expereince rather
than the vendors.

Thanks,

In this case we're talking about fairly simple things like an elec.
shaver, CD player, and so on. One device that concerns me is a battery
charger for my digital camera. I've heard some bad stories of
overcharged batteries....
