Test kits - Red Sea Pro vs Seachem Reef vs Hanna

[RGS88]

I'm looking to purchase test kits (Calcium, Alkalinity, Phosphate, Magnesium, etc.) for what will become my new reef tank , and am wondering which brand of various test kits appear to give the most accurate and consistent results... Red Sea Pro, Seachem Reef test kits, D-D, Elos, etc. (and isn't so complicated it requires an NASA rocket scientist to come in and perform the tests). I would love to get the Hanna Digital checkers. The get very good reviews on the net... but I can't justify the price... $60 for each checker with only 15 tests (for the Calcium checker for example), then another $30 for an additional 25 tests. Maybe I'm wrong, but the prices for the Hanna Checkers and refills seem high/excessive. It would cost $90 for 40 tests with the Hanna Calcium Checker (including the checker), vs $30 for 75 Calcium tests with Red Sea Pro, vs $30 for 150 Calcium tests with the Seachem Reef Status Calcium kit.
