just get yourself buffy and use webshop items that have tt value higher than top tt value since MA nerfed things a while ago, and then just hunt puny the rest of forever. You won't get markup or rare stuff (unless you count bones that you can sell), but you'll at least get back a ton of shrapnel so you can eventually withdrawal and be done...
and in theory if you are more buffy than the avatar next to you hunting the same crap you'll get better loot than them... vixens, and other non-Calypso stuff sounds interesting until you realize you don't have buyers over there and will need to ship all that junk back to Calypso going right in the middle of lootable space to sell it... and even then, just because market history shows decent markup does not mean anyone will bid if you put it on auction.
Pleak wings may be ok on markup, assuming you can stand the horrible design of that area since it's so bland and blah, and you are constantly tripping over the darn folding chairs.
If you have infinite amounts of time Monura on Ark Moon are semi-ok so long as you do the daily waypoint running to get a couple of peds ammo to make it worthwhile... but that run around waypoint thing will cost you about 20 minutes or so daily unless you burn some ped on oil and use a vehicle.... even then it'll still take a while.
