I'm a fan of Seachem tests, I've used them for over a decade. Not sure what "cheap feeling" means, but they'll measure up against more complicated and expensive tests, AND they provide a reference sample so you can test the accuracy of the kit (and your method).
Red Sea and Salifert are good too, but I always found that while everyone recommends them, not as many people actually *buy* them. Make sure you check the expiration dates on those brands, they have a rather short shelf life. Seachem has a longer shelf life. They have lot numbers (not expiration dates) if you're in doubt, call 888-Seachem with the lot number and they will tell you if it's good or not - and replace if necessary.
You won't get better customer support than Seachem.
