I would recommend the Virtual Image Pile Driver 18 IC's. The list price is $225 for a 4' pair, but right now they are at an introductory price of $175. Virtual Image also offers a 30-day return policy. I just recently bought these to A-B against some Straightwire Crescendo's, I sold the Crescendo's. If you are interested you can e-mail Virtual Image at virtualimage@juno.com. IMO, if you try these, you'll love them.
