Depending on what your definition of “decent” is, I think you may be disappointed. The cutoff for support is around 8th gen intel and AMD 3000-series from circa 2017-2018. Even my old 2017 laptop with a quad-core i5-8250U is supported.
Unless there are specific recent CPU models which are not supported, I think the majority of the unsupported laptops are going to be decade-old 6th and 7th gen or 1000/2000-series machines. These machines already go for fairly low prices on the used market.
