I guess it depends on how big of a lump you’re talking about and what you like.
I bought a Brew Magic RIMS system about 8 years ago. I love it. If my house ever catches on fire, It would be the first thing I’d save. (after the family, of course…) However, I think it requires a pretty hefty lump of cash these days. Mine was much less costly than the current iteration.
If you like to fabricate, then spend the money building a similarly designed system. It’d be less expensive and you could customize it as you like.
I’ve toyed with the conical purchase. But the logistics of my brew set-up (water, gas, ferm fridge) kind of make it more trouble than it’s worth. I bought some “Bubblers” recently and am stoked about how much I like them compared to glass.
