Food processors can run the gamut, both in price and features.
My first full sized machine was moderately priced, about $50, but it would cost a bit more now. It came with the standard processing blade as well as a reversable slicing/grating disc. This model was perfectly servicable and lasted a good 25 years before it died. Of course, manufacturers don’t make things to last the way they used to, so I wouldn’t expect today’s comparable model to last as long.
Full sized food processors can be a bit of a hassel to clean, so I also invested in a mini processor for small jobs. This one was in the $30 range back then and has served me well, but I am expecting it to burn out soon. (My nose knows)
My newest food processor was a bit on the pricey side. Retail was over $200, but we paid a good bit less. This machine has much more power and all the bells and whistles, including a small bowl for small jobs. The jury is still out as to whether it has more features than I realistically need, but I have faith in the brand and doubt I will ever need to replace it in the next 20 years.
