Simple question. Opinions???

Refractometer is accurate. Hydrometer is not reliable. This is fact, not opinion.

Ok can you suggest a good quality refractometer with a reasonable price?

Any one of these should work fine.
Amazon.com: refractometer


You can pick up calibration fluid from Bulk Reef Supply

Refractometer, even the cheap EBay ones work fine.
