Cheneti. Plenty of RES areas for bounty hunting. Lots ofLTT9097 (I think its 9097; I think. its right next door, one jump in most ships, and you're looking for a station named Fox Gateway) is also a good one. Its next to Cheneti, Imperial and High Tech. Which means lots of ships and weapons.
You also have Turir right next door as well. Its a High Tech Federation system, also with RES areas. It imports gold and has a system close by that exports same.
All in all, the Cheneti/Bloder/Turir area is a great place to call home, especially early on or if you are into combat heavy roles. So far as I know, there's not a ship in the game you cannot buy somewhere in this corridor of systems, including the Vulture, which I nabbed in Turir. Between Turir, the LTT system and Cheneti, you've got plenty of shipyards, outfitting options and tons of RES areas for bounty hunting and mining. Not to mention, you occasionally get minor wars breaking out here, due to the number of factions faffing about in this area of space.
