I made the comment because of other comments about equipment and testers that cost quite a bit of money and don't give you the value you should have if you are an amateur. Somewhere was a statement that someone doesn't want to waste paper doing test strips. But was looking for an analyzer to do the job hence the cost comparison. The cost of paper is quite low compared to the cost of some of these analyzers. It would be prudent to compare and decide for yourself, which is the best way for "you" to go. Not every answer is aimed at the original person who asked it. So take no offense at the answer.
