I was wondering how everyone measures there salinity and how much they have spent on their test instrument.

Refractometer, but do I have to say how much I paid?

Lets just say it was the only one I could find in town at the time.

Hydrometer - it might be off but it's my understanding any error is consistent so at least no S.G. swings with water changes.
