Sadly, the Chapman puts me through the same endless thought spiral. It doesn't have a conical bottom or a sampling port. Would I be willing to pay an extra $75 for the ability to take samples without opening it, over the next 30 years? Hmm. . . . And if I did make that jump, would I be willing to pay an extra $100 or so dollars for the ability to to pressure transfers, carbonate and watch the fermentation happen (Flex), again over the next 30 years? Hmm . . . And then a Unitank doesn't end up being that much more (when you add all the add ons to the Flex), but with more abilities . . .
It's truly a disease.
Good points. If you're going to make the jump to ss, might as well get the functionality you want.
Looking over Chapman on Amazon...I am rather tempted to try this version. A 14 gallon ss fermenter for $135 with free shipping. I don't do a lot of 10 gal batches, but the price might make it worthwhile for occasional use, and it would fit nicely in my ferm chamber.
