looking for a good 3d printer

[Desertboy]

I'd look at a rapsiberry pi solution, cheap as chips and can add 4" colour touch screen for a £10

As for 24v
The difference you will notice giving the nema's 24v is not like with nema 23's lol, you'll get 30% more torque but in the real world it will make almost no difference.

But the heated bed you will notice the difference I would just get a cheap mk3 aluminium heated bed, they work well at 24v and heat up in less than 2 mins, at 12v it can take over 10 mins! If you're only printing PLA I find at 12v the bed will heat to 60c in a couple of mins but to get to 110c at 12v takes forever! So 24v makes much more difference when printing ABS.
