937D+ vs #3020-XTS vs TS100/SainSmart PRO 32

[samocamo123]

As It says in the title, which iron should I get? I know most of you will probably tell me to get a used real hakko 936 or 888D but I don't want to spend that much and I don't really want a used iron. Right now I am leaning towards the TS100 but I hear the 937D+ is good and a few have recommended the #3020-XTS.
