A reseller. Yep, someone who takes your items in bulk and sells them over time to the "right" people while taking a percentage off of each transaction for his or her service cost.

I'm not even the steal-everything-that-isn't-nailed-down kind of person, but I often find myself town hopping to unload all of my potentially valuable loot while running these stores dry.

Yes, the speech perks help alleviate this but some of us less handsome and well spoken adventurers would like to pay for convenience too!

An actual vendor that has a decent amount of money. Having to travel to several different towns just to sell and still having unsold items left over=lame. Its gotten to the point where I just console command the amount of gold I would get and drop the "sold" items off into the deeper waters, or in the TestHall.

this just ruins the immersion though...

but technically, your getting more money than you should, cause the vendors always buy your stuff for less than the full value

If you invest in the Speech perks, you can give every vendor in the world an additional 1500 gold.

One gives them 500, another gives them 1000.

But a modded in vendor that has like 50,000 gold would be nice.

No, since I only give myself half of what items are worth.

Which part ruins "immurshunz", what I'm doing, or why I'm doing it?

Yeah, resorting to console commands is never what I want to do. It is a quick solution, but I always try to avoid it unless there is a non-tedius way to do it.

Being level 70 and still having loot left after travelling to every merchant in every major city is the definition of tedious. Even with master speech craft and perks, their amount is low. I have the loot to buy every house in the game twice over, but the vendors sure don't have the money to allow me to do this.

Yeah it's pretty annoying. I don't even bother selling stuff to npcs anymore, I just throw it in a chest in my house. A couple of ordinarny ebony weapons is enough to clean out most shop owners for the 2 days or whatever until they "reset". Pretty much any enchanted weapon will clear them out too.

Seems like a cheap way to make the "speech" skill tree more meaningful.

It's ok for shop owners in little towns to have 1k gold. But the shops in solitude should probably have more like 10k, whiterun/windhelm 5k, etc, etc. Not that money is really an issue anyway.
