Yes, yes it does, Brewer's Hardware, Glacier Tanks, and Still Dragon will profit nicely from you as they did me...each of them has something you need for cheaper and then its about getting the cheapest shipping after that. Still Dragon does best on shipping followed by BH, and Glacier...they aren't so good.
I bought a stainless counterflow from Williams. My plan is to do exactly as kick did, but have a welder do the work for me. However if I can't find someone to do it I will have to attempt it myself and solder as I don't trust myself to succeed with my MIG. Otherwise you could buy the TC counterflow from Morebeer...but, that is way overpriced IMO.
If you decide not to try for the TC end on the CFC I would avoid the Williams or plan to cut the threading off. They used a stainless thread that is larger in its ID than the tube's OD so there is a gap. It is welded on the exposed side. Instead of welding the side that would contact the wort and then polishing they chose to leave the gap and then siliconed it to seal, no good, they should have just left the bare pipe.
