Personally I think the syringes available from Tractor Supply do the job, they go up over 60ml and cost 1-3 dollars each. My reasoning is that while pipettes and a pump are mandatory to titrate acurately, a syringe for the volumes that you are talking are perfect.
My tastebuds won't detect the difference between .01% concentration of flavor or nic.
But LowThudd already invested in the pump and needed matching pipette for them and face it: the ease of use, the repeatable acuracy, and the coolness factor is right up there with perforated toilet paper and and sliced bread.
Definitely nice to have if you do more than tinker.
