I use a wort wizard. I actually picked one up from Petsmart for ~ $7. I think it's called a python or something like that. My kettle valve is lower than the top of my carboy but there's more than enough vacuum to bring the wort through the CFC and a post-chiller and up to the carboy cap. I use hose clamps on all of my hoses so there's no vacuum break. I can actually run the water hose fairly slow and still get the vacuum I need, but I let it water the grass anyway so I don't bother. It usually takes 15-20 mins to get 5.5 gals down to 70' and into the carboy. If your ground water is hot, then you'll still need a pre-chiller or post-chiller.
I'm going to buy a March pump, too, but not just for transferring the wort through the chiller. There are other things I want to use it for as well. An added benefit is that I'll be able to go to Better Bottles. The vacuum of the wort wizard will crush a Better Bottle - you have to use glass.
