Hard to make recommendations because there is so much choice out there. For 808 cig-alike Halo seems to be popular now. That's what I started with. It's quality and I'm still using it. Their G6 starter kit is reasonably priced for a mainstream kit at $44.99.

But then there's an 808 starter kit for only $29.95 at MyVaporStore. I don't know how it is. Looks pretty good. .

That's what happens, you keep looking and find something else more interesting than the last thing you looked at.
There's a nice 510 kit from Kanger that's only $34.95 at VaporLeaf. Only a little bit thicker than an 808 but looks sharp and discreet. And it's Kanger, a top brand. These are refillable clearomizers.

There's a cheap ego/clearo kit at MyFreedomSmokes that you can buy to try it out. After shipping it comes to $20, which is reasonable if you pretend FastTech doesn't exist, which right now you should. I like this kit because it comes with a variable volt battery. Which is not as complicated as it sounds. Three settings, no big deal.

For something more advanced there's an Evod kit at Vape Dojo for only $34.95 That's dirt cheap for this kit. It sells out quick.

edit: I've purchased at each of these vendors with no problems, except Vape Dojo which I've never bought anything. I'm sure they're fine. I do want that evod kit.
