Anyway, I use these numbers and find they do the trick:
fBarterBuyBase: 5.0
fBarterBuyMult: -4.0
fBarterSellBase: .1
fBarterSellMult: .7
You will find a huge difference in your finances. I have even found myself putting the odd point in Barter at lower levels!
Another suggestion is to reduce the ridiculously large carry weight. That stops you from grabbing every damn thing that isnt nailed down and becoming a pack rat. I currently use a base weight of 60 and augment this with a backpack. When I loot its mainly looking for the odd rare bullet to supplement my meagre stock.
Using a bullet weight mod is also a big help. No more hauling around thousands of rounds of 5mm that I don't even use!
Yes, I've done all that, except for the reduced carry weight. Which I would find frustrating frankly. I've also done more, like cut the amount of gold I get for Pre-War books in half, tripled the repair cost for my gear, increased the cost of the household stuff. My latest move is to make Bottlecap Mines cost 10x as many caps to make, up to 100 caps now instead of 10. I've also increased their weight. How much sense does it make that you need a Lunchbox and a Sensor Unit for them, with a combined weight of 3 lbs, yet the mine itself only weighs .5 lbs? I've also increased the weight of the other mines, and their cost. Why is a Frag Mine that's 3x the size of a Grenade and more powerful the same weight and cost? I've doubled both. There's some other things I've done as well, but it's still nice to have that reduced stuff from the areas I visit that the Unfound mods provide. I'm finally starting to find the kind of balance I've been looking for after all that

Excellent, thanks. I'm glad you can still find the time to work on this mod.
