EFI choices?

'68 390 GT running a Performer RPM intake with Edlebrock 750 carb. For drivability, especially spring & fall (cooler weather) I'm seriously considering going to a throttle-body EFI setup. Preferably on the Edlebrock intake manifold.

What are the current choices? I've visited the RetroTek site, and like the idea of the returnless fuel line system... looks as easy as it gets for a conversion. Any experiences with this, or other EFI systems?

Thanks
Phil
 
I ordered the RetroTek today. Had to get it through Summit. Apparently RetroTek has been bought by Professional Products and they tell me that the whole online store for direct ordering on the RetroTek website isn't used (even though it all appears live). Online pricing etc is all out of date. And they don't sell direct to the customer anymore.
 
I've been eye balling the new Holley Avenger EFI. There are a lot of options available (multi O2 sensors, timing control, etc) and it is self learning.

Unfortunately it's so new I don't think anyone has used one on a Ford yet.
