Resuggest. Wide ranges aren't uncommon nowadays so this is ok, I think.

Conclusion :

Sales below 4 ref are all outliers because they happened before the update and buyers counter them. Most sales at 6-7 ref. One seller at 5 ref with some in stock. If more at 5 ref pop up I will resuggest. Well, there are some in classifieds below 6 ref and one on OP with 4 more at 5 ref, so I guess 5-7 ref it is.
