Hi,
My wife and I started vaping about 4 months ago.  We got an inexpensive starter kit with vision spinner, CE4 tank, and charger.  We've already had to buy about 8 CE4/5 atomizers and have had problems with all of them.  Only two work now.  But then they only cost $3 at my our ecig shop.  I know opinions differ, but which is the best tank to buy that will last for some time and that the coil can be easily replaced (cost around $10-12.)?  I'm not interested in mods and giant tanks, not yet anyway 

.  Also, where can I get really reliable batteries at reasonable cost.
Thanks and happy vapin',
Randy Boulter
