I voted:

- calibre - because I will want it for a specific hunting purpose.

- price - because while DRs for higher prices than my wallet allows might be wonderful, if I can't afford them I can't buy them.

- function - I assumed this included workmanship. ie if it is a DR and doesn't balance or doesn't feel right at my shoulder, then it would be purchased. Similar if I want or don't want ejectors etc. Weight? A suitable weight for the chambering and the purpose it is wanted for. A lightish .470 might be OK if it is not shot a lot. But if it kicks too much, the owner probably won't use it much or enjoy it much or at all. A too heavy 9.3mm or .400, why bother with it? Balance and fit is the most important.

- accuracy was not mentioned. Obviously a newly made DR is expected to regulate very well. Accuracy within the bounds of the use of the calibre.

- I did not vote reputation, however this certainly helps with the re-sale value, if the owner wants it to appreciate in value over time or sell it again one day.

Some my reasoning.
