The DM5 brain is out of the question for me because it doesn't have an aux input. I liked the Hart, but their Prodigy set didn't have the features of the DTXpressII. The DTX set has a 3-zone snare and one of the cymbals is 2-zone. Plus the hart comes with the DM5 - I know you can buy just the pad set, but I didn't want to look around for a separate module.

If you have a Guitar Center near you, that's their price. Probably because Yamaha is coming out with their DTXpressIII set.
