Just wondering if there's a change between LTR-32123S and LTR-40125S except the speed difference? I'm not a speed addict, and I'm upgrading from a x6 burner

so either x32 or x40 won't hurt my eyes. Don't know if there's a difference in the built or functions between the burners.
There's a 90€ gap between the two, money that I can goodly use for other components.
Any reply appreciated
