I did a lot of digging before buying my first MODs too... I purchased an HCigar Copper Penny clone and an HCigar WindRose clone. I really loved the feel and all copper body (and contacts) of the Penny! I had never touched the WindRose before ordering one, but understand they are very similar to the Cartel in the weight and thickness of the smooth brass tubes. It should arrive tomorrow or Friday (depending on local PO), so I'll find out very soon if it was worth it!
I also considered a Hammer, Cartel, Stingray, Turtle Ship V2, and Overdose... but the Penny was a must-have for me, and the WindRose was "something different" with a really eye-catching Compass-Rose design
