3D Printing: Which hotend does not clog and is good to use with a Bowden 1.75 mm setup?


The Question: I'm building my own 3D printer (custom design, made by me and cut using a water
cutting machine) but I have always had problems with the hotend clogging.
I have had four hotends:
 * a J-Head;
 * a full metal;
 * a full metal made by me and;
 * my current hotend which is just a block of aluminium with a plaster cold-
 end 100% homemade with no precision at all.
Believe it or not, this hotend is the only one that has finished a whole print
(about 40 minutes), all of the others, with or without fans, haven't managed to
finish one!
Well... this hotend has a 1.5mm hole so I guess that that's why it can print.
The problem with all of the others was that the 1.75mm PLA that I'm using
clogged the hotend after two minutes.
Now I would like to buy a new, more precise, hotend. I'm using a Bowden
extruder, can you suggest a good hotend?
This is my printer:
