The thing that Bens kit had going are the extra reagents for the commonly used ones. Personally I don't do the OTO test but that's my preference. For the K-2006 kit the CYA reagent (R-0013), Calcium buffer (R-0010), FAS-DPD titrating reagent (R-0871), and the DPD powder (R-0870) get gobbled up first so you can order larger bulk refills of those. Keep the bulks refrigerated and closed, except to refill the smaller bottles, and they last a real long time. Years.
