The best way is to use a length of hose filled with water. You place your thumb (or a clamp of some sort) over the end you want to drain from (ie. the outlet) and lower the other end into your fermenter. Now place the outlet lower than the fermenter (well it actually only has to be lower then the surface of the beer) and remove your thumb or clamp. The liquid will flow.
There are probably a few ways to do this more sanitarily, including filling the sterilized hose with boiled water and using a clamp instead of your thumb (or you can kink the hose back on itself). The trick is to no let the water in the hose flow back into your fermenter, which just takes control of your thumb or clamp. Make sure you drain the initial water into another container to dispose of before transferring into your vessel.
Another method is to sterilise your hose well, then lower nearly the full length of hose into your full fermenter-letting the hose fill with beer (the problem here is it might disturb your sediment). You don't have to dunk the whole length of the hose, keep 6 inches of so for you to hang on to. Now block the end your hanging onto with your thumb or a clamp and pull the hose out over the side of the fermenter (don't pull it all the way out so the other end pulls out). The hose should now be full of beer, release you thumb or clamp and the liquid should flow.
I suggest practicing with a couple of buckets of water to perfect your technique before trying it with beer.
By the way, what's wrong with using the tap on your fermenter. Most brewers out there do it this way with no problems whatsoever. It is much easier and probably more sterile in the long run anyway.
You can also get special siphoning hoses that have a marble or ball in the end that you jiggle. You can buy them from auto stores. Sterilise it and away you go.

Or do it Warrens way, which sounds very good too.
