I am right there with you, I would order one of David's drippers right away also.
I have a black bf hornet, I have it on a reo grand and I love it! You can't go wrong with that one. It is smaller than the ERA but also a very easy build.
Have you checked out the immortalizer by Chief Vapers Pat? WOW, thing looks awesome! Shipment has been delayed but as of right now looks like it will be coming to the states as of the 15th. Totally stoked about that one! I am on that list and it can't get here soon enough.
Here is a video on the immortalizer before revision.
Here is a picture of the inside after the revision.

Also have a nimbus that is in the air now as we speak. Should be here by weeks end. You can run quad coils on that one, and the price is very very reasonable for a SS dripping rba!
