Hmm ?,.oral ecstasy ?...... i could give you a couple of phone numbers

You may want to have another go at explaining the problem. It's not clear what you are asking for ?

If you can get past the phobia of only buying new, warranty, nice packaging , etc etc,... ..then you can find some incredible top line equipment, generally well cared for ...( coffee drinkers tend to be sensible folk !),..in the " For sale" section. At the worst, a new set of burrs may be needed

I read it as the OP wants an E61 group, that doesn't need any cooling flushes, and rotary pump. Most E61 group machines can be set up to eliminate the cooling flush..easier on some than others...and it takes some expertise and patience to calibrate suitable boiler temps and Thermosyphon restrictors ...

Try throwing a tea towel over the group head, and flushing brew water through as soon as the boiler is up to temp ! When you learn how to do this , and keep the boiler element on most of the time, you can have the group up to temp (& stable) in under 15 mins !

Ahh !.. Well then , just buy a steamer and sit it beside the Zafiro ! Which group for a dual boiler ?.. The E61 has proven itself to work superbly on DB machines already, but the ideal would probably be a saturated group (LM etc) Note:- in effect the E61 on the Zafiro

You do understand that grinding for espresso needs fine adjustments ? One mark on the dial can be the difference between a good shot and a disaster.! Moving 2 marks on the dial could be the difference between a 15 sec shot , and a choke shot ! Hence the Teflon tape mod to allow part step adjustments...

Ingenious conversion ! But why did you see the need for a "funnel" of any type ? You could simply extend your tube down to the PF holder

Messy grinding is mostly down to organisation of equipment and technique. I have used several different doser less grinders (Rocky, Compak, Fiorenzato, etc) ,..all of which can be messy , but if you set the PF holder correct, use a dosing funnel (or yogurt pot cut down !).. And change your technique...
