I asked around, and I don't know anyone who has beaten the price I got for apr. The giac group buy here was going to cost more, by a lot.
As for which one is better, I have no idea. But, this was an interesting read:

It's the closest thing I've seen to a fair comparison between the ecu tuners. About the only thing better this guy could of done was to have another a4 that was left in stock and dynoed on that same dyno each day they ran tests. That way you could have a better idea of how much variance the weather had on hp.
Still, it's nice to see how much power you gain from an ecu mod, and those were all the 91 octane programs, I've got the 93 :->
