I have the same problem so I found a great DIY site. They are having a big Christmas sale and I was able to get PG/VG nicotine, PG/VG plain and 10 different flavors of my choice with everything else needed to do it for $36. Had to pay $15 shipping but it came out to less than $2 for a 30ml bottle of juice. Just got it yesterday so i'll play with it today. Here's a link if you're interested.
