Nope, your coils don't look too bad at all... I wish my first few coils turned out that nicely!
I'm not looking for a trade, but I think you'll be very happy with the larger size... makes it easy to work with as a first-device, and excellent air-flow... One piece of advice is to position your coils directly over the air-holes, or slightly "inside" the holes so the air comes directly under the coil, or slightly to the outer-edge... this will give you much better vapor and flavor (less airy and weak).
If you're looking for a standard-size, I've seen them for ~$15-18 (even less if you buy from one of the better Chinese vendors, but shipping is slow). If I run across a decent price, I'll shoot you a link
