I dropped by Vicous Ant's office yesterday and got one. Apparently, the local dealers don't carry the bottom-fed version so I had to get one directly from Vicious Ant. Cost me about $49.

I'm now on the hunt for an AFC cap. They didn't have one laying around the office so I have to go to one of their authorized dealers.
I haven't built it yet since I sent it to my friend who has a machine shop to drill an extra feed hole. My experience with the Hornet has taught me that if the feed hole is anywhere but on the bottom of the post (or deck-level) there is a tendency for fluid to remain on the deck. It won't flood but it causes performance to vary and adds a risk of spilling
juice from the feed hole. I won't get it until me and my friend meets again (which may take a few weeks).
I'm in no rush though. This will go on a new Grand I'm planning to buy when the new contacts are out. The RM2 is serving me well anyway at the moment.
