There are two on eBay right now:

The one for 140 is a ridiculous price. No need to pay that. Also, you can source a lot of parts on hondamarketplace.com. I've been using that to find the little bits and pieces. For instance I found the P07 and the 5 wire on there for 95 shipped (O2 was used for a month), and I found a wiring harness I can hack apart to add to my CX harness to effectively create a VX harness, and it was 35 shipped. A lot of good finds for the vigilant buyer. And I've seen a P07 on there recently as well in the Mid-West specific forum.
Good luck, and happy hunting.
EDIT: Word of warning, the people at hondamarketplace are all tuner kids, not the same crowd as you find here, so just be ready when they mouth off.

On the up side, I've bought 4 items from there in the last so many weeks, and all have been good deals and good sellers, but as with all things, buyer beware.
