If shiznitz means great investment that makes the job easier and faster, me too. I love mine.
Buy thick scrapers and not the thin ones.
If you don't do that, go for roto brush anyways. My first season back after my rotator cuff tear was a breeze with regards to tuning because of the roto brush. I didn't have the electric scraper sharpener yet, but the roto brush only requires the strength to hold the drill level to the ski base and squeeze the trigger. Way easier on the shoulder. Being normal size (5'7") makes brushing a ski in a vise at normal counter height require more arm/shoulder strength than for someone closer to the abnormal 6' in height. The roto rush really did make doing four pairs of skis at a pop a breeze.
Some folks scrape less because it is easier to roto brush more. I'm not a fan of that but it is better than scraping only.
The electric scraper, though pricey for what it is, is a vast improvement over using a file, sandpaper, sheet rock screen and the rest. It takes about 2 minutes to master.
Though not required, I clamp mine to the bench so I can hold the scraper with two hands. Others hold the sharpener with one hand and scraper in the other. Just a preference.
HOWEVER, now that I have an electric sharpener and my shoulder is good, I find myself grabbing my hand brushes more often.
You could always go for the double shiznitz and get both
