It depends a lot on your budget but I would buy separate items. sometimes kits have items you really wont wind up using.
You can find 32oz bottles of PG and VG out there for $33 dollars (both $33 total) w/free shipping (@ essentials depot) which will be enough
juice for many, months if not longer. some kits only provide a 60 or 120 ml bottle of each which doesn't last very long.
you can find good quality Nicotine in various Mg levels and sizes (if you choose to use nic. in your
juice) at Wizard labs along with a variety of flavorings as well.
when you buy higher level nic juice from Wizard labs they throw in a pair of gloves.
I also advise that you shop around different flavor vendors for a flavor or two you might like. (buy the smallest sizes to start)
capellas has some nice flavorings and are very good quality.
You can get syringes very cheap at Wal-Mart (buy some 1ml size... like .40 cents each) even free for some sizes (5ml and 10ml) if you just ask the pharmacist for them, say you need them to administer meds to your kid, or family member.
rinse well old or empty juice bottles to start with you can buy bottles later (about 25 to 30 cents ea.)
That should get you started supplies wise. best advise is to download the E Juice me up calculator and play around with it to figure out how it works.
make only 5ml batches to start.
begin w/10% flavoring to start and work up from there as needed.
Best of luck!
