Conicals are nice, but I'm quite content with my carboys and they're definitely cheaper to control temp on. Plus some of the beers that need to sit for a while can be easily shuffled off into a corner and I've still got a few carboys I can ferment in. I don't really see myself switching over, just not quite enough bang for the buck for my current batch size and frequency.
