Use them all the time. Depending upon your access, and where you need to get, there are almost unlimited options available--everything from electric narrow-carriage models to 150' booms (not reccomended for your application
)
If you do rent one, make sure the driver has a suitable place to off-load the machine and most places can give you a basic run-down on how to operate it (and they should).
Controls are pretty straight-forward, and there isn't much sway in the smaller booms--especialy articlauting (like your photo). To be extra-safe--wear the harness and lanyard which are (usually) supplied with the machine and tie-off to the approved point in the basket.
Practice away from the home (and any obstructions) until you get the hang of it--keep it in SLOW(turtle icon) and make note of any power lines going into the house and keep away from them (15' minimum)
Have fun with it--clean your gutters while you have it and maybe even check your chimney flashing and brick mortar. Trim pesky branches, etc.
