I just bought R-0003 and R-0871 from van isle water. It's cheaper than buying a whole new Taylor kit but it's still pretty expensive. However you get 60ml bottles and I probably need 15ml myself. So if you'd like to "buy in" let me know! Quadra/McKenzie area. I don't deliver, sorry. You bring your old 22ml reagent bottles here and I'll fill them 3/4 full for $25 total.
