https://wiki.project1999.com/Hammered_Golden_Loop Is probably the cheapest item with the most HP per slot. At 60 you will get over 200 HP just from wearing a pair, assuming you are not STA capped. Obviously the -AC sucks, so their mileage does vary based on the kind of content you are doing.
EDIT: Missed the part of your message where you said you are in Planar and Darkforge. Grats on getting to 60 in paper on a Dark Elf
[You must be logged in to view images. Log in or Register.] There are quite a few cheap HP options in that case.
https://wiki.project1999.com/Barbed_Dragonscale_Boots AC is on par with lower tier velious armor like Thurg plate, and you will get at least 60 HP, assuming no STA cap.
https://wiki.project1999.com/Silver_Chitin_Wristband The gold standard of melee bracer until you can get something like scout bracer or raid armor. 80 hp from two of them.
Quite a few good suggestions above as well, but I am assuming at the moment things like Vindi BP may be out of OP's price range or raid expectation, same with pegasus belt.
