DIY is easy when you have limited start up funds. To this day all I use is a 12 ml syringe, a stainless steel condiment cup that I got for a dollar at Wal-Mart and those 30 ml leftover bottles I mentioned, plus a few 10 & 5 mls for experiments. I buy my nic base and other ingredients from Wizard Labs; small amounts of flavors from them are actually a bit cheaper than from the source. For larger flavor amounts I order directly from the source, Perfumer's/Flavor Apprentice. For any bottle that I can't get a syringe into (I use them without the needle) like the flavoring, I pour it into the condiment cup and pull up the amount I need from there, then pour the rest back. For syringes though, make sure you're getting the etched ones, not the ones with the inked markings. I started with an inked syringe and the nic base tends to fade the markings quickly. I purchased my current syringe plus a few extras at a veterinary supply. My mix space is in the kitchen on a tray to prevent any spills and covered with a double ply of paper towels to soak up any drips. Easy.
