Karen:
The Leslie's kit and the Taylor kits I mentioned are chemically the same--Taylor MAKES Leslies' kits for them.

Ben's kit, the PS-234 is basically the same, and I believe it's chemically the same (the PS-233 certainly is). Ben gives you better instructions, more refills, a log to record stuff, and leaves out the useless acid demand and base demand tests. But you need this RIGHT NOW and he can't get it to you that fast. So plan B) is the Taylor or Leslie's kit.
