Regarding the state of the aftermarket EFI offerings, I confess I haven't looked seriously at them for several years. When I did look about five years ago, I was surprised by the ready availability of "factory refurbished" units. I had to wonder why the manufacturer had so many returns they could carry a large stock of refurbished units. The most likely reasons (faulty components and high difficulty of installation) caused me to drop them from consideration.
