I assume you mean equipment wise. Trying to order flavors on amazon would be like hunting for a specific mosquito in the jungle. The main question concerning equipment is how obsessed with accuracy are you? Beakers are a good start no matter which way you think your going to go. For the obsessive-compulsive a Pipette Pump and some pipettes will have you completing each step with perfect accuracy. You may also want a pipette rack. For the impatient or frugal-minded folk some syringes will work fine for measuring. Handling the nicotine requires some care so you will want some gloves. You may also consider goggles for added protection. Dropper bottles are really expensive on amazon.com. You can also get some of the above at http://wizardlabs.us

Edit: oh, I almost forgot stir rods
