I didn't say your kit was a rip off; I said they (beststore) sell old tech kit at rip-off prices. I you got a deal, you got a deal. Can't say fairer than that.
If you ever need to find out the price of something, look on myepack (London) and that's middle of the road prices, not as cheap as Amazon/ebay (ebay is a bad idea generally) but less than some of the big chain stores.

The good news though is that although you have a Joyetech eGo-C battery, you don't have the original eGo-C atomizers and cartridges, which was my main concern. Those systems are dead, gone... thank goodness. They were really bad and very costly.
The best small clearomiser is probably the Aspire K1 BVC. Or the Eleaf GS air.
I get small items like this and replacement coil heads from Fasttech.
