Best hot end

I recommend the SG2 or europa hot end, they are the best you can buy, and they have the best customer service. never jammed, very durable and well engineered, and bradley will make you whatever size nozzle you want, very nice guy.

Just seems to me, that any of the design that relys on plastic in the hotend is going to be suspect in the long run. The one above by theodlief, or the commercial Stepstruder from makerbot (http://store.makerbot.com/stepstruder-mk7-complete.html) have no plastic. No plastic = nothing to melt/deform/break. I'm using an MK V-B, J-Head hotend, and it oozes just a bit, at the brass/PEEK joint at temps over 225. It works well for me, but I've never tried ABS, still "learning" with PLA.

It seems to me that this entire thing (RepRap) is about using printed parts, and low cost. Any 3D printer would be more reliable if it used NO plastic parts, but then that is not practical !

Since all those webshops mentioned above with the Budaschnozzle and the J-head are sold out...

Will this be a nice alternative?

I think the reprap project can have different values for different people. For example, while I can definitely appreciate the ideal of a 'self-replicating' machine, the machines that I use would place precision, quality and accuracy as a priority over cost or reprap print-ability.

Just wanted to comment on the original hot end that was posted by the OP,

I have tried it. It failed imidiatly and jammed, Was never able to really get it to print.
