Take it as a sign: With a LF you wouldn't be on the horns of this dilemma;-)

Give it a try with a battery, on ebay they sell some as a package for less money. My girl also uses such a modern thing with a power station and we pay more than 30 Eu for one battery at the shop ... on ebay 15 Eu for 6 pieces ...

give it a try, selling the camera could be an option for later ...
