Howdy spog,
I have always been a fan of syphons over taps and have tried probably all of them. I've written here exactly what I would want form the perfect syphon and you wouldn't believe what showed up in the mail the other day

but more on that after I do my next brew in a fortnight.
I was actually given a stainless steel version of the jiggler syphon you are talking about. I would not even consider using a plastic one of any sort unless I knew it was food-grade as no matter what temp you are transferring at, many plastics will impart an infected flavour to beer even at low temps.
So, did my stainless steel jiggler work? No. It kept stalling as it's diameter was too big. There are also two size plastic auto-syphons as well. Do not buy the larger diameter one. It will stall as well!!!
Cheers,
PP
