Edelbrock Pro-Flo 2 EFI advice?

A friend of mine has a 350 and just bought factory vortec heads and now wants to go EFI. The Holly commander-950 looks inexpensive but the edelbrock pro-flo 2 looks really complete, easier to install and maintain too perhaps. It looks like everything needed from soup to nuts for $2900

He is looking for tunable performance and economy. Anyone here have any experience with edelbrock's EFI?

He was planning to run a milder cam than what edelbrock suggests for the 35000 model which fits the vortec heads, I wonder how that would work out... Any advise or opinions on that aspect would be appreciated too.

I was hoping you would get some feedback from someone who has used the ProFlow 2 software and user interface. I am looking at their new ProFlow XT as I don't necessarily need the "carb look". The new software supports direct programming as opposed to their old chip based system, but I have not seen any feedback from users to date.
