I purchased NECWIN BASIC from Nittany Scientific (for around $78) a few
months ago and have been very pleased overall with it. It is particularly
good at modeling wire antennas that have elements close to ground, because
of the Sommerfield ground simulation routine.
 I have modeled wire HF antennas, a proposed tower installation (checking
for guy wire interaction), and homebrew VHF/UHF yagis, quads, and quagis.
 I never used modeling software before and this package seems like a good
one. I think it is well developed for the price. I particularly like the
viewing module where you can view your antenna in simulated 3D from any
angle, and print it as well. I use this feature as a cover page for the
stack of plots I inevitably make for each antenna configuration.

 See http://www.nittany-scientific.com/  They also offer a full-blown
version.

Find and read any and all articles about modeling and the quirks involved
with the NEC code that modelers such as this one are based on.

 Take a look at L.B. Cebik's (W4RNL) excellent site for starters:

Jump in, the water's fine!
