i looked into a lot of dremels comparisons in 2021 and 2022
and a lot of sites an youtube videos
in the end the 4000 Kit went on offer at amazon from around £189.99 down to about £132 - that decided me simply the price
I have used mine a few times and its been fine

https://www.dremel.com/au/en/p/drem...l 4250 runs cooler and,with EZ Lock Nose Cap.
I also got a small multi chuck, multi vice, drill press, router attachment, and separate big box of bits , guard - also all on offer
from amazon
All for under the orginal price just for the kit - watched the price for a long while
I was looking at the cordless , but wanted at least 2 batteries and was not on offer
I also considered alternatives, watached a lot of videos , BUT ot was the price that decided in the end
