I have to agree, unitaskers are all about whether you have the space and the need. I made brandied cherries this year and I'm not even sure how I could have done it without a cherry pitter. I also have a big citrus press, but if I need to juice a bunch of lemons or limes, not regretting the other 90% of the time it just takes up space. I'm sure many other people are like me, I have a bunch of big multi-taskers: stand mixer, blender, and food processor, some of which have feature overlap, but again certain things they are best at.
The one multi tasker that I need though is an insta-pot, then I can ditch my slow cooker and rice cooker.
