For 200 mil you should be able to get one with about 1050 DPS, a socket and >0.23 APS. I think that'd be ideal for you.
Personally I think your current weapon set is fine, although you can drop Bloodthirst and run Tough as Nails or Superstition as 11.5% LS is kind of unnecessary and they'll buff your EHP more.
I'd also upgrade to a socketed IK helm and CC lacunis (low end) before I upgraded to an EF. I think it's a good idea to get solid weapons, which you already have, and then upgrade your gear set around them before you up your weapons again. You should be able to get both of those for well under your 200mil budget. The better your ancillary items are, the more DPS a weapon upgrade will add.
Your andy's will be murdering your EHP with the extra fire damage and in unsocketed which is pretty crucial for a helm.
Of coz i did enknowledge your way of geaing is a gd budget setup. 200mil is not small. With goodbuy, you can get pretty top items. I just feel OP should get a big buy with this 200mil. Before doing smaller upgrades as they can be easily done later.?Many times we dont get such big amount of gold for one shot investment. Use it well OP.
At his gear level though I think it might be a good idea to upgrade his set with 2 100mil buys rather than one big buy on an OH weap. I completely agree with you about spending at least 200mil on a buy when you're around my level of gear, but as I said above, I prefer to upgrade the set around decent weapons and then drop big cash on weaps. That's how I did it running with two weaps similar to my current ones but about 1/4 the price all up. And then when I upped the weaps it boosted my paper DPS by about 25K in one hit, and boosted by tDPS by about 200K.
I realise a solid IK helm won't be anywhere near 100mil, but low end CC lacunis will be pretty exspensive and they'll make a bigger difference to both DPS and EHP I think.
