I use my Hanna Alk checker pretty much every day. It's likely an overkill, but the solution isn't prohibitively costly and the actual test is easy. Based on the reviews from BRS, it's a pretty accurate reading, but I've not yet confirmed that.
I've got the Red Sea kit on the way (for Calc and Mag testing, mostly) and I'll be doing a few cross-checks as well (because why not). Other reviews I've seen gave the impression that the other testers (Cal, Mag, and Ph) were not as effective. I'll likely pick up the complete set at some point as they are easy enough to use and likely accurate enough to serve for "every day" use. I'll keep a more accurate/reliable test kit around so that if I get any numbers that seem strange, I'll use the kit as a "second opinion".
One thing that I would suggest if you're doing every-day testing would be to pick up a 10ml syringe. Filling the vial exactly to the 10ml line certainly is not hard, but it's a lot easier if you can just use a syringe to suck up just the right amount every time.
Note that I like the idea of testing every day. I'm a pattern/numbers kind of person, so I like to have lots of data points to help me figure stuff out. I'm sure that I'm doing way more measuring than is needed, so if I were following a more normal testing regime, the Hanna checkers would likely not have as much of a draw.
