Glad you got it sorted -esp. since I know how frustrating it is when you've gone for what should be (and is) a first-rate set-up and it doesn't work right for some stupid reason...
As far as high quality liquid... Since they're an approved vendor here I hope it's OK to link
Open Source Vapor.
No PG in these juices but I don't really care about PG- doesn't bother me one way or the other. I DO, however VERY much appreciate the approach of "This is exactly what I put into this stuff I'm selling you to inhale. Here are the ingredients, the ratios, and where they come from." THAT part I very much appreciate. Also, all flavours I've tried are great, free domestic shipping, and prices more than fair to begin with.
