I needed 30 of the 20700a cells and I heard a rumor that the Dewalt dcb206 has them built in.
So I bought a pack and low and behold, 10 of these beauties.
Online, these cells are going for 18 dollars a cell. If you break it down, you would get these cells for about 9 bucks a pop.

The welds are extremely strong and I damaged the first few cells by pulling the welds off incorrectly and leaving little pin holes once the negative terminal. I got a little bit of leakage in 2 cells. So I went ahead and soldered the negative terminals. I need to do a capacity test on those 2 cells but who knows they may be trashed now.
