Red Bear mini, bit outdated but should be fine.

1:1 for a HG Fortunate Son(~73)

No minis for anything else, you're right.

I got a sale for the Wrench:

Sold for a Cool Shot to Hell Pistol(Battle-Scarred)(23 Keys)*, a Silver Cyclone Battin' A Thousand(23 Keys), a Vivid Plasma Hard Counter(13 Keys) and an Australium SMG(8 Keys at the time)(67 Keys total)

*Pistol has no mini, though there's a seller at 23. This should be good enough for the wrench as a mini: http://backpack.tf/classifieds?tradable=1&craftable=1&australium=-1&item=Pistol&quality=5&particle=703

If you count the old-ish Red Bear Shotgun mini, both weapons combined should be ~150. All we need now is a sale for the Scorching Herald's. Although with Glitch Daddy's insane B/O, I doubt we'll get that anytime soon unfortunately.

NOW, If we take a blind guess at the Herald's price(which we all know is somewhere in the range of 100-240), here is the sale's contents:

-Sunbeams Polar Pullover(1900 Keys)

-Scorching Flames Coldsnap Cap(400 Keys)

-Holy Grail Rancho Relaxo(142.5 Keys)

-Isotope Red Bear Shotgun(Field-Tested)(73 Keys)

-Isotope Torqued to Hell Wrench(Battle-Scarred)(67 Keys)

-Scorching Flames Herald's Helm(~100-240)

Not valuing the Herald's, the sale comes out at ~2583 Keys total, so the highest possible value for the sale would be ~2823(Valuing the herald's at a full 240), and at minimum at ~2683.

Personally, I would wait and see if the Herald's can resell so we can find at least a reasonable value for it. Although valuing the sale at say, 2700 wouldn't be far off. My opinion though, as some mods might disagree with me on this. I can still see this suggestion passing as being better than the current though.

Needless to say this will need a range, as with or without the herald's value this sale is already a few hundred keys higher than 2235.
