I can't say enough good things about my Nemesises (Nemesii? Nemeses? Nemesen?). I've got stainless steel, brass, and copper - all clones and all fantastic performers. My brass one from FastTech actually has crap threads and i can't even use it anymore, but before that it was hella tight. Even a great clone shouldn't run you over $50 generally, and the ones from FastTech are generally perfectly fine at around $25.
I use Kayfun, Taifun, and RSSTs. IMHO, RSST is about the easiest way to learn how to start building your own coils. Almost nothing can go wrong and they hit like champs. Nothing sublime - but they work great and are super easy to deal with. On days when i just don't feel like screwing around, i drop a wick in and wrap it, screw it down and start hitting. Boom, done. And no dumping of juice while i do it. Clones of any of the three above RBAs are around $25-30, more or less. RSSTs can be had even cheaper.
