DHPs have been tough to find for a while now... I would be playing with OBD2 V6 stuff now if I could get ahold of one when I don't immediately go broke seconds before one gets posted for sale with a reasonable price. being able to use just the somewhat more attainable AVT cables(and not having to screw around with a serial-USB adapter) is helpful, but I have yet to see anyone post definitive proof of being able to just plug in and go.
