Yep, good rental company should have those. Especially on battery-operated gear the chance of getting something good is high.
I have used a few battery-operated units and sold a few to customers. The good ones have prices upwards of 1100 euros. The ones below that, not worth their price. And I have tried and tested many.
Since your probable use of battery-operated gear in the future will be limited (if not buy the best you can afford above a certain minimum quality), rental does make the best sense.
Where you use it, nobody cares, as long as you return it back on time 😀
