Take a look in the E-Juice section here. I'm kinda new myself <than 1 mo. but have gone biserk over e-juice since my 1st kit had "USA Mix" (tobacco) incl. I ordered 3 bottles my 1st try and luckily got 1 that I love. That was from ElixerLiquid.com. I ordered RY4, 555 & Cinnabun (the awesome one).
My next order was a 10 pack sampler from JuicyVapor.com and the only one I really went gaga over was Lime-In-The-Coconut. Surprised the hell outa me, but I like Key Lime Pie, so... anyway I thought all the other flavors were blah and not powerful enough.
My last order was from OneStopDIYShop.com and ordered the 38mg PG juice and 4 Perfumers' Apprentice flavorings. The "DIY Artisan Kit" is a good one from OneStop. The good one here, IMO is Cinnamon. Powerful taste & vapor. Other one of note was Jamaican Rum...woah! It's powerful too. Flavors as low as 1.50 for 6ml, which goes a long way.
I was lucky to get in the TastyVapor group buy 6ml No-Nic variety(called "doublers" by TV). That order is on it's way.
I guess my point to this reply is that you will probably spend a lot of money on finding the flavors you like no matter who the vendor. As you can see my favorites are far different from each other...that's just the way it goes I spose.
The best thing about the DIY shops are that you can mix the flavors however you want to achieve "your" favorite juice. They are pretty cheap too.
