Zdyne is a wopping $1,000. $950 for them to just chip your ecu, Not including the ~$350(at least) for someone to tune this system. I also didn't see any options for anything obd. Only non-obd ecu's.
You also have to send your ecu to them and wait for it to return.

I personally like Hondata. For it's excellence all the way around, and ability to pay for upgrades later, and not have to deal with things you don't need yet.
