I started out with an auto siphon, broke it, bought another, broke that, then went to regular siphons pushing with CO2.
I found trying to do a closed system was too complicated and troublesome for me, and I also thought it was a waste of CO2, so I went to a more rudimentary setup.
I now use a stainless racking cane, and to start the siphon, I use a sanitized turkey baster, and breathe in to create the vacuum and start the siphon, then once the beer begins to flow, I remove the turkey baster, and then put the tubing end wherever it needs to go.
I find that with racking, I prefer my setup to be simple. We all choose where to complicate things and where to add gadgets, this is just one area where I went back to the basics, and it has worked well for me.
I would recommend trying some different methods and see what sticks with you and fits with your style the best.
