The DF83 was initially priced at £799 for the stock italmil (is it still the case?) in the U.K, and now at £699. One may still need to buy a mazzer or SSP burrs set.
Importing it can cost between USD 600 and USD 700 plus VAT, import duty, postage, replacing the burrs and risks of return costs should there be an issue.
Compared to these two choices, IMO, the duo is priced well. Yeah! it’s fair enough that the prospects should have been given the choice of choosing one or both burrs to help them save some £££ depending on their choice.
I did wonder why Niche didn’t give this choice to the users. Only they can explain.
Re-the pricing and VAT for the non-UK users, this has been discussed and documented extensively even on this forum. It suffice to state that it does limit their market reach, considering the alternatives.
Edit :
MattH has echoed similar thoughts on pricing while I was drafting mine.
