I understand that if you really want to take advantage of buying and selling stuff to merchants, you should dive into the speech perk.

I just hate it when I buy 10k worth of training/weapons/apparel from an NPC and return to resell them more loot after a dungeon dive and have their gold reset to the default (2k for this particular NPC)

makes it very difficult to sell stuff.

As for the balance of gold in the game, so far i think its pretty balanced, i make a lot of gold selling potions but i also spend a lot when i have NPCs train me at a skill (especially around the 70-90 range)

i have 60 hours clocked in playing as a level 41 khajiit assassin. (100 in sneak/alchemy/archery) (aiming for enchanting last, i think)

I wonder how good the mods addressing the economy of the game will be

how are you guys making money... as an alchemist, you can sell potions that have a value of 2.25k (which is like 1k to vendors)

Alchemy is easy to make money with.

I have smithing maxed out. So I just buy gear from guys, improve or upgrade them and sell it back. Get about twice what I payed for it.
