I have used (1) ice bath, (2) first attempt at IC (too tall), (3) second attempt at IC (short and squat, but I didn't like stirring my wort to keep it in touch with the coils), (4) CFC (I love this thing).
When I am done mashing, I clean the tun. Near the end of the boil I use the tun to run Starsan through the CFC and then directly to the fermenter to sanitize that. It is very easy. I do not have a pump. I just use gravity. When I am done running the wort to the fermenter I run Oxyclean and then clean water through the CFC. It is ready for next brewday.
This summer my ground water has gotten warmer, and I have only been able to get the wort down to 73F. I have thought about using the old IC in an ice bath, but so far, I have just moved the fermenter to my basement, and I pitch the yeast about a half-hour or hour later. I'm just guessing that the temp has dropped a little, but I don't really know. The basement is at 68F this time of year with the A/C on, and I have bubbles in the airlock within 12 hours usually. So, it's working for me. We'll see what the fall brings and the heat comes on.
I have been considering a fermentation chamber, but I'm still not sure exactly what or where I want it.
