I went with these. They cost $7 per pair, so though a little more expensive than the others, but they're still in the ball park. Also no soldering and no crimping mean they are easily reusable.
Rat Shack Banana Plugs
You can't tell from the photo, but all you do is unscrew the plug (you can see the line where the two parts separate about midway down the base of the banana plug), stick the stripped end of the wire up through the lower half of the separated plug, gently bend the individual strands of the wire back down over the lip of the lower half, and then screw the top half of the plug back on. They hold tightly, and securely. I'm very happy with them.
On the web page you can check to see if your local Radio Shack has them in stock.
