Clones are cool, depending on who made them. I especially look for HCigar clones. Many of their clones rival the authentics quite closely. Another company that's doing great work, and unlike HCigar, they are still building mechs, is YFTK. Steam Gear tend to be really good as well.
The big difference between clones and the more expensive authentics is the fire buttons. I've gone over a few, sanding them smoother, giving them an ultra-light coat of silicone lube, replacing springs with stiffer ones, and upgrading magnets. I've also converted a couple to magnets instead of springs.
In many cases, you can buy authentic replacement buttons.
Here's a nice Caravela clone from HCigar, with a very nice and cheap Matrix RDA clone. Great setup for under $20.
