I think the TF100 is an improved format over the K2006, so don't take this the wrong way this is just some honest feedback.
After purchasing some reagent replacements from a local Taylor distributor, I feel as though the quality of the drop bottles and especially the DPD powder container in the TF100 is lacking.
With the bottles, it is very difficult to get a consistent drip size. I realize this has been stated here before and the issue is with static - but I've not had the same issue with the Taylor bottles - I feel they are more consistent and easier to control.
The bigger issue though, is the DPD powder container. It's not air tight, and in just a few months of humidity the powder gets clumpy and begins to turn red. I know the clumps are not a big issue, but turning red definitely is. I have not gotten accurate results unless the powder is pure white, otherwise it does not dye the sample correctly. I had the 2 containers side by side, and the Taylor container seals super tight which in my case resulted in a better shelf life.
Just my $0.02
