Which Densitometer to Purchase?

[ic-racer]

I have a Tobias that I bought inexpensively years ago. While it's "accurate" within a range of densities, I value it mostly for comparative measurements only.

I have two Tobias and I'd not part with them. What exactly is wrong with yours? I was able to get parts for one of mine a few years ago right from Tobias as they are still in business.

Recently one of them needed a new switch that was easy to find at Mouser. Other than that they are both still working great and read perfectly.
