I personally would suggest a kanger sub tank, the fullsize, mini, or the nano. Mostly because these tanks are a great deal. They come with a rba section if you want to start rebuilding your coils in the future, but also have changeable coil heads that I'm sure your failure with. I think these are just around $50 and come with a bunch of goodies. It's a solid deal.
The aspire nautlis full size, and mini are great. if you get one of these I strongly recommend getting the bvc coils.(bottom vertical coils. Better flavor)
The aspire atlas seems to be pretty popular to but I don't know too much about it I'd suggest looking this one up.
An ipv mini 30 watt, there is a ipv mini 70w coming out soon, The Istick 30w's/40w's/50w's are pretty popular, small, and effective. I've heard good things about the sxpro mini and the new vamo mods.
I ordered my ipv mini from elev8pe and used a coupon code "Jan15" to get the price down to $46 and I believe the shipping was free.
If price is not an issue I'd high recommend a hana mod dna 30 or 40. They are just awesome, look great, have some sweet features like temperature control but you'll have to rebuild your own coils with pure nickel wire to be able to use the temperature control feature. It basically means you'll never get a dry burnt hit again.
I hope I helped.
Whatever it is you buy I just hope you do some soild research on what you want and make sure your using a reliable and safe vendor. Happy vaping!
