Opinions on new fuel sender

Hi,I need to replace rhe sender on my 68 dart so I can get rhe gauge working again.
So far I've read nothing but bad things about the new "repro" fuel senders. Supposedly none of them will have the gauge read correctly which is the whole purpose of installing a new sender.
Are the senders from Vans any different? If not does anyone know of an exact repro that does or a source for a good rebukt.original? Thanks
