Any bio/chemfags here with experience with these bad boys? I know they have been replaced by a variety of more accurate machines, but other than refurbished Spec 20s or the occasional cheap digital specs I see on amazon, I don't see much in my price range.

For reference, I am a hobbyist who just discovered how accessible these are as analytical instruments, and would like to purchase one to begin my dream of analytical device accrual. I'm going to start by practicing on known samples, do some brass Cu analysis, hopefully some basic plant constituent, protein, and water impurity analysis as well in the future.

It seems like the Spec 20s were very common for a very long time, and I don't mind the analog approach (kinda dig the vu meter look). But also want to know if it's worth getting a cheaper low grade digital one, or if it's worth just saving up for a $1000+ spec.

Thank you in advanced.
