€250 electric grinders to switch from J-max

Update: Got the Eureka Mignon Silenzio after a €70 discount coupon from work! Thanks for all the answers!
Hi! So I have a robot and J-max for 6 months now, but I injured my wrist and J-max is only allowing me to grind dark roasts (still with a lot of pain). I want to sell my J-max and get an electrical grinder. Do you have any budget-friendly suggestions? My max budget is €250.
