Wow. First I an very interested in knowing more about your fermenter. Are you really filling a 20 gallon vessel with beer??
But besides that, you can easily siphon using some cheap parts. This is one thing I do:
Add a "T" (mine's stainless, but a food grade plastic T will work fine) in the racking hose. It should be placed high enough up on the hose to allow your hose to reach the bottom of whatever you are racking into. Place a pinch device on the short piece of plastic coming off from that T.
What you will do is block the long end with your sanitized finger while sucking on the short part. This will cause the siphon to start. Once it's started, pinch the short hose closed.
THIS KEEPS YOUR NASTY GERMS FORM EVER REACHING THE BEER.
You can also pick up what's called an Autosiphon, which is like a siphon pump. They are not too expensive, but if you don't have ready access to a store then it might be harder to get than a simple T and pinching device (like a pair of vice grips, or an actual plastic pinch clamp)
I prefer both of these methods to the old fashioned sanitizer you hands and dunk the whole siphon hose into the beer and plug the ends while pulling one end out to put into the secondary.
Lastly, you may consider not using a secondary for most beers. A lot of people are finding that there is no danger to their finished beer by leaving it in the primary for several weeks, and some feel it actually improves their beer brewing by eliminating that extra step.
Of course you'd still need a siphon of some sort for bottling/kegging...
