I had dug up some other sales but they involved outdated hats or things I just didn't want to deal with and I was far too lazy to do a mini when I had these other sales that required no additional work to use. Additonal sales at 1.5, another at 1.1, and a third with a specialized item that is at least 1.5 so I think the range I have now works fine but I can resuggest if you have a different range in mind after these extra sales.

Offered on (and sold for) a Smoking Barnstormer (~1.5, 9 months outdated but most B/Os are at 1.5 right now)

Offered on (and sold for) an Orbiting Fire Ol'Snaggletooth (~1.1, 6 months outdated and a clear low end outlier)

Sold for Specialized S.F Sniper with parts (hast to be at least ~1.5 between the parts and rifle alone and since the sniper was sold for an Australium Medi-Gun which was 2 buds at the time)
