hotend - which one? (1 reply)

hi,
I'm buying a prusa i3 from [www.3dprinters-shop.com]
And they have diferents hotend to choose:
-J-Head Hotend 3mm / 0.50mm nozzle
-Buda-style HotEnd v1.2 - pre-assembled 0.4 &0.5 nozzle

What are the diferences between them? Is the expensive one better?

thanks :)
